# Geometry Practice Test 1

##### 1. Which of the following letters represents the vertex in the following picture? 1. D and E
2. E and H
3. F and G
4. G only
5. H only
1. 6.28
2. 12.56
3. 25.13
4. 50.24
5. 100.48
##### 3. What is the area of the triangle below? 1. 22 cm2
2. 33 cm2
3. 44 cm2
4. 50 cm2
5. 66 cm2
##### 4. What is the measure of the solid line angle depicted by the following figure? 1. 90 degrees
2. 180 degrees
3. 225 degrees
4. 270 degrees
5. 0 degrees
##### 5. What is the measure of angle B in the following figure if angle A measures 135°? 1. 40°
2. 45°
3. 50°
4. 135°
5. 225°

###### 1. E

The vertex is the point, formed by the two rays of an angle. Thus, H is the vertex of the angle.

###### 2. C

C=πd. Substituting 8 for d gives C=8π, where C is approximately 25.13.

###### 3. B

The area of a triangle may be found by using the formula, A=1/2bh, where b represents the base and hrepresents the height. Thus, the area may be written as A=1/2(11)(6), or A = 33. The area of the triangle is 33 cm’.

###### 4. D

The sum of the angles, formed by the perpendicular rays is 360°, thus the curved arrow represents an angle measure that is equal to the difference of 360° and 90°, or 270°.

###### 5. B

Since angles A and B are supplementary, the measure of angle B is equal to the difference of 180° and 135°, or 45°.
