Let's solve the problems step by step.
Problem 1: What is represented by figure ABC?
The figure ABC consists of two rays originating from point B and extending through points A and C. This forms an angle at point B.
-
Line: A line extends infinitely in both directions.
-
Ray: A ray has one endpoint and extends infinitely in one direction.
-
Angle: An angle is formed by two rays sharing a common endpoint (vertex).
-
Point: A point is a single location in space.
Since the figure ABC shows two rays meeting at a common point (B), it represents an
angle.
Answer: C. angle

Problem 2: Which is a line?
We need to identify which option represents a line. A line extends infinitely in both directions.
-
Option A: This is a ray because it has one endpoint and extends infinitely in one direction.
-
Option B: This is a line segment because it has two endpoints.
-
Option C: This is a line because it extends infinitely in both directions.
-
Option D: This is a point because it is a single location in space.
Answer: C

Problem 3: Which figure shows a line segment?
A line segment is a part of a line that has two endpoints.
From the given diagram:
-
Figure AC: This is a line segment because it has endpoints A and C.
-
Figure DFE: This is not a line segment because it extends infinitely in one direction (ray).
-
Figure ADC: This is not a line segment because it extends infinitely in both directions (line).
-
Figure BD: This is a line segment because it has endpoints B and D.
Both Figure AC and Figure BD are line segments, but we need to choose the correct option based on the provided choices.
Answer: A. Figure AC
