Are the two triangles below congruent? Make a sketch of both triangles, then determine all of the angle measures and all of the side lengths. If they are congruent, describe a sequence of rigid transformations that maps one onto the other. Note: The triangles are not drawn to scale. Homework Help ✎
Use the Pythagorean Theorem to determine the lengths of any unknown sides.
Remember that all the internal angles of a triangle add to 180°.
Try creating an equation to determine the measures of the unknown angles.
Now that you know the unknowns, are the triangles congruent?
