Mhanifa please help! Explain how you can use the perpendicular bisector of a segment to draw an isosceles triangle.
Anna007 [38]

Answer:

If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.

To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B

1) Given: mLHE=84°<br><br>Find: m∠EYL. <br><br>2)Given: m∠EYL=72°<br>Find: m arc EHL, m arc LVE
SCORPION-xisa [38]

Answer:

Part 1) The measure of angle EYL is 96\°

Part 2) The measure of arc EHL is 108\° and the measure of arc LVE is 252\°

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Part 1)

Let

x------> the measure of arc LHE

y----> the measure of arc LVE

we know that

x+y=360\°

x=84\°

Find the value of y

y=360\°-84\°=276\°

<em>Find the measure of angle EYL</em>

m

substitute the values

m

Part 2)

Let

x------> the measure of arc EHL

y----> the measure of arc LVE

we know that

x+y=360\°

x=360\°-y -----> equation A

m

m

substitute

72\°=\frac{1}{2} (y-x)

144\°=(y-x)

x=y-144\° --------> equation B

equate equation A and equation B and solve for y

360\°-y=y-144\°

2y=360\°+144\°

2y=504\°

y=252\°

Find the value of x

x=252\°-144\°=108\°

therefore

The measure of arc EHL is 108\°

The measure of arc LVE is 252\°
