A carpenter wants to make a triangular bracket to hold up a bookshelf. The plan for the bracket shows that the vertices of the triangle are R(−1, 3), S(2, 5), and T(2, −1). Can the carpenter conclude that the bracket is a right triangle? Complete the explanation. The slope of RS =

3

.

The slope of ST = undefined.

The slope of RT =

3

.

There are

(select)

two sides for which the product of the slopes is −1, so

(select)

two sides are perpendicular. This means the triangle

(select)

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
