Question

A) What type of triangle is triangle ABC? b) Give reasons for your answer. I just need B​

Answer 1

Answer:

isosceles triangle

Step-by-step explanation:

line CB is the transversal for the two parallel lines, so angle CBA and angle BCE are the same.

since a straight line is 180 degrees, we can solve for angle BCA by subtracting the other angles on the line from 180

180-80-50 = 50

since triangles have 180 degrees, we can solve for the last angle by subtracting the angles we already know from 180

180-80-50

two of the angles are the same, making this an isosceles triangle
