Two Congruent Triangles

For Students 9th - 12th Standards
See how parallelograms can produce congruent triangles. Given a diagram of a parallelogram, scholars must show that two triangles are congruent. The triangles are made from the diagonals of the parallelogram.
Lesson Planet

Diagonally Half of Me!

For Teachers 9th - 12th Standards
Cut straight to the proof. Given cutouts of different quadrilaterals, pupils draw diagonals. Learners cut up the figures along the diagonals to see whether they bisect each other. Scholars develop a geometric proof for the property they...
