# Unit 2 Classwork 2

## Name the vertex and sides of each angle.

1) Diagram with point O and angle with sides labeled P and R.

2) Diagram with point C and angle with sides labeled A and B.

## Name all the angles that have \( V \) as a vertex.

3) Diagram showing lines intersecting at point V with points labeled as B, C, and D.

4) Diagram showing lines intersecting at point V with points labeled as J, K, and L.

## Classify each angle as acute, obtuse, right, or straight.

5) Diagram showing an angle labeled as \( x \).

6) Diagram showing an angle labeled as \( y \).

7) Indicates a 90-degree angle.

8) Indicates a 28-degree angle.

## Name the relationship: complementary.

9) Diagram showing two angles labeled \( a \) and \( b \). 

**Note:** Complementary angles are two angles whose measures add up to 90 degrees.

- **Page 1 / 2** 

This exercise is designed to help students understand angles, classify them, and explore their relationships.

**Name the relationship: complementary, or linear pair.**

10) Diagram: Two angles, ∠a and ∠b, share a vertex and are adjacent. One side of both angles forms a straight line (linear pair).

**Find the measure of angle b.**

11) Diagram: Two angles are adjacent. One angle measures 64° and shares an arm with angle b.

12) Diagram: Angle b and a 54° angle are adjacent.

**Find the value of x.**

13) Diagram: A straight angle marked as (3x + 19)° and 101°.

14) Diagram: Two adjacent angles, one marked as (2x + 17)° and another angle measuring 31°.

15) Diagram: Two adjacent angles, one marked as (x + 19)° and another angle as part of a straight line.

16) Diagram: Two angles on a straight line, one marked x° and the other not marked.
