Math Problem Statement

Which congruence statement is true given that KL bisects ∠PKQ?

Solution

To solve this problem, let's analyze the given information and determine which congruence statement is correct.

Given:

  1. Triangle PKQ\triangle PKQ with points PP, QQ, and KK.
  2. KLKL is a line that bisects PKQ\angle PKQ, which means it divides PKQ\angle PKQ into two equal angles: PKL\angle PKL and QKL\angle QKL.

Objective:

Identify the correct congruence statement.

Solution:

Since KLKL bisects PKQ\angle PKQ, we know that:

  • PKLQKL\angle PKL \cong \angle QKL, as they are the two angles created by the angle bisector KLKL.

Therefore, the correct answer is:

  • PKLQKL\angle PKL \cong \angle QKL

This corresponds to the first option on the list.

Answer:

  • PKLQKL\angle PKL \cong \angle QKL

  2. How can we determine congruent triangles within a bisected angle in a triangle?
  3. What other properties of triangles can be used to establish congruence?
  4. How do we use Side-Angle-Side (SAS) or Angle-Side-Angle (ASA) in proving triangle congruence?
  5. Why is it significant to have congruent angles when analyzing triangle properties?

Tip: Remember, an angle bisector divides an angle into two equal parts, which can be useful in identifying congruent triangles or angles within a shape.
