Think & Click: Congruent Triangles
Now, you try. Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
Triangle ABC is congruent to triangle XYZ.
Find the value of x.
Since side BC is congruent to side YZ, 2x + 3 = 25, x = 11.
If the measure of angle A equals 47 degrees, the measure of angle B equals (8y + 8)°, and the measure of angle Z equals (4y + 5)°. Find the value of y.
Since the triangles are congruent, angle C is congruent to angle Z. The three angles must add up to 180.
47 + 8y + 8 + 4y + 5 = 180°
y = 10
