Using the information on the protractor, explain how to determine the measurement of the angle. What is the measure of the angle?
angle 1: outer in between 160 and 150 inner between 20 and 30
angle 2: Outer in between 50 and 40 inner 130 and 140
To determine the measurement of the angle using the information on the protractor, you need to align the baseline of the protractor with one of the sides of the angle. Then, locate the vertex of the angle at the center of the protractor.
For angle 1:
- The outer scale reading is between 160 and 150 degrees.
- The inner scale reading is between 20 and 30 degrees.
To measure angle 1, you need to align the baseline of the protractor with one side of the angle while keeping the vertex at the center of the protractor. Then, determine the reading on the outer scale and the inner scale where the other side of the angle intersects with the protractor.
Using the given information, angle 1 is measured as approximately 160 degrees on the outer scale and approximately 20 degrees on the inner scale.
For angle 2:
- The outer scale reading is between 50 and 40 degrees.
- The inner scale reading is between 130 and 140 degrees.
To measure angle 2, align the baseline of the protractor with one side of the angle and keep the vertex at the center of the protractor. Then, find the reading on the outer and inner scales where the other side of the angle intersects the protractor.
Based on the given information, angle 2 measures approximately 50 degrees on the outer scale and approximately 130 degrees on the inner scale.
