What is the perpendicular bisector definition?

• If a segment is a perpendicular bisector => it divides a segment into 2 congruent parts and then forms right angles

• If a segment divides a segment into 2 congruent parts and forms right angles => the segment is a perpendicular bisector

What is the right angle definition?

• Right angles are 90 degrees

• If 2 angles are congruent => they are right angles

• If 2 angles are right angles => they are congruent

• Right angles are shown by a small box at the vertex of a triangle showing that the angle is 90 degrees.

How do you solve for HL?

• The triangles need to have a right angle symbol and a congruent side to prove they are congruent by Height & Length

• If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent

• They are always congruent

• Right triangles are never congruent until you can solve for CPCTC.
