Answer:

b. SAS

Step-by-step explanation:

These triangles can be proven congruent through SAS, or side, angle, side. SAS is used when two sides and one included angle are congruent. For an angle to be included, it must be in between the other two sides. This means the angle's rays are the congruent sides. If two lines have an equal number of tick marks, or if two angles have an equal number of arcs, then they are congruent. In this image, two line pairs are marked as congruent as well as the included angle. Therefore, the correct answer is B. SAS.

given that ABCD is a parallelogram, find each of the following
AB
AD
< A
< D

Answers

Answer:

AB = 8

AD = 10

<A = 118

<D = 62

Step-by-step explanation:

1. AB

Because opposite sides in a parallelogram are equal, DC = AB = 8.

2. AD

Because opposite sides in a parallelogram are equal, BC = AD = 10.

3. <A

Adjacent angles are supplementary in a parallelogram, so A = 180 - 62 = 118

4. <D

Opposite angles are equal in a parallelogram, so B = D = 62

Answer:

AB = 8

AD = 10

m∠A = 28°

m∠D = 62°

Step-by-step explanation:

A few facts to remember about a parallelogram.

1.  Opposites sides are congruent

2.  Opposites angles are congruent

3.  Consecutive angles are complementary

So, AB = 8,  AD = 10,  m∠A = 90 - 62 = 28°, m∠D = 62°
