Question

Jada drew a line segment and marked its midpoint as A. With A as the center she used the compass and created a 180 degree angle by drawing an arc. She marked point B on the arc and point C to the left of point B, on the arc. She used a straightedge to connect A, B, and C.

What type of triangle did Jada construct?

Answer 1

a- An equilateral triangle, because the lengths of all three sides of the triangles as the same as the radius of the arc.

Answer 2

b- An isosceles triangle, because the lengths of at least two sides of the triangle are the same as the radius of the arc.

Answer 3

c- An acute triangle, because all vertices are to the right on the arc.

Answer 4

d- An obtuse triangle, because one vertex is to the left on the arc.
