We can use the angle bisector to construct some other angles from existing angles. Which diagram shows a construction of a 45ο angle? A 15˚ angle can be obtained by bisecting a 30˚ angle. It is also the line of symmetry between the two arms of an angle, the construction of which enables you to construct smaller angles. 1) 3) 2) 4) Regents Exam Questions G.G.17: Constructions Name: _____ www.jmap.org 2 3 Using a compass and straightedge, construct the bisector of the angle shown below. [Leave all construction marks.] From the vertex, draw an arc across both rays of the angle. The point where these two new circles intersect and The arcs intersect above and below the segment. An angle bisector is a line that cuts an angle in half. Here are the steps to constructing an angle bisector. Your IP: 159.65.218.200 This can be performed by creating a 60° angle and then … Consider the construction of the angle bisector shown. 1 Which illustration shows the correct construction of an angle bisector? For example, if we draw angle bisector for the angle 60 °, the angle bisector will divide 60 ° in to two equal parts and each part will measure 3 0 °.. Key Concept - Angle Bisector The angle bisector divides the given angle into two equal parts. Which illustration shows the correct construction of an angle bisector? Angles ∠ DAB and ∠ DAC are equal. How to bisect an angle with compass and straightedge or ruler. 10 Using a compass and straightedge, construct the angle bisector of ∠ABC shown below.
