Question

Bob draws a line segment AB and draws a perpendicular line that intersects AB at C. He places the compass at C and draws an arc from B to A. He plots point D on the perpendicular line and on the arc. What triangle did Bob construct with the points C, B, and D?

Answer 1

A. An obtuse triangle because the measure of one angle is 90˚.

B. An acute triangle because two angles measure less than 90˚.

C. A right scalene triangle because one angle measures 90˚ and all sides are of different lengths.

D. A right isosceles triangle because one angle measures 90˚ and at least two sides are congruent.
