1st ESO ART. Unit 7.4 Constructing angles and bisector

The bisector of an angle is the line that passes through the vertex, dividing it into two equal parts. Each point of the bisector is equidistant from the sides of the angle.

BISECTOR OF AN ANGLE



When we work with set squares we need to know perfectly well the measure of their angles to use them:



Using the set squares we can draw 45º angles, 90º angles, 30º angles and 60º angles. But combining them we can draw more. Se this example images constructing angles with set squares:
