Finding the angles of triangle KDM

To find the angles of triangle KDM, we can use the information given about triangle KLM and the properties of isosceles triangles.

Given: - Angle KLM = 80 degrees - KL is a side of triangle KLM - KD is the bisector of angle KLM

We can start by finding the measure of angle KDL, which is half of angle KLM because KD is the bisector of angle KLM. Therefore, angle KDL = 80 degrees / 2 = 40 degrees.

Next, we can find the measure of angle KDM. Since triangle KLM is isosceles, we know that angles KLM and KML are equal. Therefore, angle KML = angle KLM = 80 degrees.

Since angle KDL is 40 degrees and angle KML is 80 degrees, we can find angle KDM by subtracting the sum of these two angles from 180 degrees (the sum of the angles in a triangle).

Angle KDM = 180 degrees - (angle KDL + angle KML) = 180 degrees - (40 degrees + 80 degrees) = 180 degrees - 120 degrees = 60 degrees.

Therefore, the angles of triangle KDM are as follows: - Angle KDL = 40 degrees - Angle KDM = 60 degrees

I hope this helps! Let me know if you have any further questions.
