Basic Geometry Test 1 Solution

#### 1. Match each word with the correct statement. Write the letter on the line.

We need to match each term with its correct definition.

- i. Point: A specific location in space.
- Correct match: b. An exact location in space.

- ii. Plane: A flat surface that extends endlessly in all directions.
- Correct match: i. A flat surface that extends endlessly in all directions.

- iii. Angle: The shape formed when two rays meet at a vertex.
- Correct match: f. The shape formed when two rays meet at a vertex.

- iv. Ray: Part of a line having one endpoint and extending infinitely in one direction.
- Correct match: a. Part of a line having one endpoint.

- v. Parallel Lines: Two lines that move in the same direction but never meet.
- Correct match: h. Two or more lines that move in the same direction but never meet.

- vi. Line: A series of points that go on endlessly in both directions.
- Correct match: g. A series of points that go on endlessly in both directions.

- vii. Perpendicular Lines: Two lines that intersect to form a right angle.
- Correct match: e. Two lines that intersect to form a right angle.

- viii. Intersecting Lines: Two or more lines that cross or meet each other at a point.
- Correct match: c. Two or more lines that cross or meet each other at a point.

#### 2. Write acute, obtuse, right, straight, or reflex to describe the angles below.

We need to classify each angle based on its measure:

- a. The angle is less than 90°.
- Classification: Acute

- b. The angle is greater than 90° but less than 180°.
- Classification: Obtuse

- c. The angle is exactly 90°.
- Classification: Right

- d. The angle is greater than 180° but less than 360°.
- Classification: Reflex

- e. The angle is exactly 180°.
- Classification: Straight

Final Answer for Question 2:
```
a. Acute
b. Obtuse
c. Right
d. Reflex
e. Straight
```
