Solve for the area of the circle shown.
153.86 ft squared
100
Solve for the measure of angle b.
b = 112 degrees

Will the following side lengths make a triangle? Explain your answer.
3 feet, 4 feet, 8 feet
No, because when you add the two smallest sides together they are less than the biggest side (3 + 4 = 7, and 7 is less than 8)

Solve for the measure of angle a:
28.9 degrees
100
Can the following angle measurements make a triangle? Explain why or why not.
12 degrees, 85 degrees, 20 degrees
No, because the sum of the angles is not 180 degrees.
200
Solve for the circumference of the circle shown.
31.4 ft

Ms. Latouche drew a triangle. What is the measure of the last angle?
78 degrees
200
Are these triangles unique or identical?
No, because the position of the side lengths are different on the two triangles.

Describe the angle relationship between a and b.
Angles a and b are complementary.
