Question

Are the triangles similar?

Answer 1

Answer:

No, because the sides lengths are not proportional.

Step-by-step explanation:

What is the SAS similarity theorem ?

By definition, two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional.

What is the AA similarity theorem ?

If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.

• They both have an angle of 70°
• This lies between sides of 6/9 and 9/18 respectively for the triangles
• 6/9 = 2/3 and 9/18 = 1/2
• Hence, the sides are not proportional
• They are not similar

Answer 2

No because The side lengths are the same
