Hypotenuse-Leg (HL): Quick Exploration

Below, we have two right triangles. Here, the [b]hypotenuse[/b] and [b]leg [/b]of one right triangle are congruent to the [b]hypotenuse[/b] and [b]leg[/b] of another right triangle.

Test to see if these two right triangles are congruent by trying to place one on top of the other. Note: LARGE POINTS and some segments are moveable.

Are the two triangles above congruent?

No Yes

If you answered YES to the question above, which rigid transformations did you use to superimpose one triangle on top of the other?

Rotation about point Translation by vector Reflection about line

Show the 2 right triangles are congruent below. Reflect one triangle about the line if you need to. LARGE POINTS & some segments are MOVEABLE.
