**45-Degree Angle**

When two rays crossing at a usual endpoint, they form an angle. The typical endpoint is dubbed the vertex, and the beam are dubbed the eight of the angle.

You are watching: What is the opposite of 45 degrees

An angle is measured in° or radians. If the 2 arms of one angle expand in exactly opposite directions, the is a right angle. A straight angle measures 180°. One angle can be measured utilizing a protractor, and the angle of measure 90 degrees is called a right angle. In a appropriate angle, the 2 arms space perpendicular to every other.

When the right angle is split into two equal parts each angle measures 45°.

**Constructing a angle using a protractor**

**Step 1**: attract a ray and also name it AB.

**Step 2**: keep the center point of the protractor in ~ A. Because the angle opens up to the right, select 45° in the list that starts in ~ the right and also moves in the anticlockwise direction. Mark the suggest C.

**Step 3**: join A and C. Here, procedures .

Constructing a angle utilizing a compass

**Step 1**: draw a heat segment and also the perpendicular bisector of by intersecting the arcs the radius more than half of the length MN. Allow the perpendicular bisector crossing the heat segment at O.

**Step 2**: attract an arc focused at O with a radius OM, cutting the perpendicular bisector in ~ P.

**Step 3**: sign up with M and P utilizing a straight line. Actions .
