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.

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 .
45 level Angles in real Life:
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
Constructing a angle utilizing a compass
Step 1: attract a line segment and also the perpendicular bisector of by intersecting the arcs that radius much more than fifty percent of the size MN. Permit the perpendicular bisector intersect the line segment in ~ O.
Step 2: draw an arc focused at O with a radius OM, cutting the perpendicular bisector in ~ P.
Step 3: sign up with M and also P using a directly line. Steps .
