## 45-Degree Angle

When 2 rays intersect at a common endpoint, they type an angle. The common endpoint is called the vertex, and the beam are dubbed the arms of the angle.

You are watching: What does an 80 degree angle look like

An edge is measure in° or radians. If the two arms of one angle expand in precisely opposite directions, the is a directly angle. A right angle steps 180°. An angle can be measured utilizing a protractor, and the edge of measure 90 levels is called a best angle. In a right angle, the two arms room perpendicular to every other.

When the right angle is separated into 2 equal components each angle actions 45°.

Constructing a angle utilizing a protractor

Step 1: attract a ray and also name the AB.

Step 2: store the center point of the protractor at A. Because the angle opens to the right, pick 45° in the list the starts in ~ the right and moves in the anticlockwise direction. Note the allude C.

Step 3: join A and C. Here, steps .

Based top top the location and also climate the the place, some solar panels are installed at an angle of 45° for optimal solar power production
