Applies Triangle Congruence to construct perpendicular lines

It is a point that divides the segment into two congruent parts.

• center

• endpoint

• midpoint

• vertex

Point X is the midpoint of 𝐴𝐵̅. Which of the following is true?

• 𝐴𝐵̅̅ ≅ 𝐵𝑋̅̅

Reflective Learning Sheet

Based on what you have learned in this WEEK 8, perpendicular lines and angle bisector mean a lot to mathematics. But is usefulness will not be seen unless apply into reality. I want you to look around in your house and find structures that shows perpendicular lines and angle bisectors. Give at least three and cite its usefulness in the house.

Example: door – It is formed by perpendicular pieces of wood.

It is important structure in the house because it serves as

passageway to the kitchen, bedroom, corridors, and the likes. Without a door no one can enter or out in the
