**Explain how to use a protractor to measure an angle. Put**

The used the interactive protractor to measure, and also their own. They then used these angles to create their own abstract art. They traded papers and made a chart of estimated angles, actual angle measurements, and type of angle.... To do both tasks, you use a protractor, a very useful tool to keep around (see Figure 1). Figure 1: The handy-dandy protractor. When choosing a protractor, try to find one made of clear plastic. Figuring out the measure of an angle is easier because you can see the line for the angle through the protractor. The breeds of angles. Several different angle breeds, or types, exist. You can figure

**Explain how to use a protractor to measure an angle. Put**

To measure an acute or obtuse angle: . Put the cross-hairs at the centre of the base line of the protractor on the point of the angle; . Align one zero on one arm of the a … ngle (keeping the... Unlike a regular protractor, a bevel protractor is adjusted to fit the angle. The base is placed on the bottom side of the angle, whilst the blade is moved to match the opposing side. In addition to a degree scale, many bevel protractors will have a vernier scale on …

**What Is Angle? Cut-the-Knot**

Explore and explain how to use a semicircular protractor to measure a reflex angle (Communicating, Reasoning) Extend the arms of an angle where necessary to facilitate measurement of the angle using a protractor (Problem Solving)... Here is the order: Place the center mark of the protractor on the angle's vertex. Place the zero edge of the protractor on one ray. Use the greater number for an obtuse angle and the lesser number for an acute angle.

**Measure Angles with a Protractor Guided Lesson Explanation**

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.... Measure Angles with a Protractor - Guided Lesson Explanation Explanation to #1 An acute angle measures less than 90°, but more than 0°. A right angle measures exactly 90°. An obtuse angle measures more than 90°, but less than 180°. One ray is already lined up with 0°. Follow the other ray to find the angle measurement. This angle measures exactly 90°. This angle is a right angle. Name

## Explain How To Use A Protractor To Measure An Angle

### A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Two angles with the same measure are called congruent angles.

- 4/06/2007 · Best Answer: Take the little hole at the bottom and line it up with the bottom line of the triangle/angle. If the triangle or angle you are measuring is small like a pair of scissors a little under halfway open then look at the smaller numbers to measure, it is called acute.

- According to the student, to approximate the degree measure of an acute angle, simply mark the two sides of the angle at 3 inches from the vertex, measure the distance between these points, and multiply by 20. The result, according to the student, is the degree measure of the angle…
