Hypotenuse Angle (HA) Theorem (Proof & Examples)
Geometry may seem like no laughing matter, but this lesson has more than one HA moment. That's because this is all about the Hypotenuse Angle Theorem, or HA Theorem, which allows you to prove congruence of two right triangles using only their hypotenuses and acute angles.
Video Summary
Though it may not have been a barrel of laughs, by exploring the HA Theorem you are now able to recall and state the Hypotenuse Angle (HA) Theorem, demonstrate the HA Theorem's connection to the Angle Side Angle Theorem, and mathematically prove the HA Theorem.
