Coordinate Geometry Teacher Resources

Challenge the class to devise a method to determine the dimensions of a rectangle inscribed in another rectangle. Pupils make connections between functions and geometry as they examine the area and perimeter of a square or rectangle...

Tenth graders explore analytic geometry.  In this geometry lesson plan, 10th graders use analytic geometry to investigate the attributes of geometric figures.  Students investigate the slopes of lines and the length of line segments as...

Verify a figure by using coordinates. Pupils calculate the coordinates of the midpoints of the sides of a quadrilateral. They then use the coordinates to show the resulting figure is a parallelogram. 

Coordinate the vertices of a rectangle. Pupils use the location of three vertices of a rectangle along the axis to find the coordinates of the fourth vertex. Using the vertices of the rectangle, scholars prove the diagonals are congruent...

Don't be a square! Young mathematicians determine the slope and length of a line segment. They then prove whether four given coordinate points form a square.

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it...

High schoolers use Cartesian coordinates to plot current natural disasters. They relate location of natural disasters to their specific major project countries. Students tie in geometry within this instructional activity as connected to...

You'll be spinning in unit circles once you read through this jumbo-sized resource of everything you need to know about trigonometry. Each page has color-coded examples with explicit directions that detail the problems and formulas. 

Students investigate the ties that architecture and math have in common. They focus on works of architecture in the world that is considered of great significance. Students use the internet to find building images from around the world....

Have you ever wondered how computer animations work and what type of math is involved in making objects move across the screen? In this task, your young computer animators will use the geometric transformation of translations,...

Need to build a laser fence on Mars?  In this cute maximizing-area lesson, young explorers pretend to be prospectors on Mars and must determine the best way to use 20 meters of fencing in order to maximize their area. In addition, they...

Students use Cartesian coordinates or degrees of latitude and longitude to locate important locations within their specific countries. They Use a grid to apply the concept of latitude and longitude, or positive and negative Cartesian...

Students find coordinate points on a grid and create a line graph with those points. This lesson should ideally be used during a unit on various types of graphs. They make and use coordinate systems to specify locations and to describe...

Students identify different properties of parallelograms. In this geometry activity, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.

Learners calculate the area and perform translations. In this geometry lesson, students identify and solve simple equations to calculate the are of a rectangle. They relate algebra and geometry together as they solve problems.

Learners use the unit circle to solve problems. In this geometry lesson, students identify missing sides and angles using the unit circle. They identify trig ratios using the unit circle.

Students study how coordinates in space are used to produce special effects in movies. They locate a point in space, and then use the distance and midpoint formulas to find points in space.

Students investigate and solve Pythagorean triples. In this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.

Students investigate the Pythagorean triples. For this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Young scholars differentiate between ellipse and hyperbola. In this algebra instructional activity, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Learners investigate the relationship between angles of triangles. In this geometry lesson, students identify properties of right and non-right triangles. They differentiate between vertical and supplementary angles.

Young scholars find missing angles and sides of triangles. In this geometry lesson plan, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.

Students relate the ratio of Pi to the diameter of a circle. In this geometry lesson plan, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and diameter and find...

Students investigate symmetry in the real world. In this geometry lesson plan, students inter-relate math and technology. They create and name a variety of polygons.
