Classify each triangle by its angles and sides Please help!!
a. ABE:

b. BEC:

c. DEF:

d. CDF:

a. Right triangle

b. Isosceles

c. Equilateral

d. Scalene

Step-by-step explanation:

a. ∆ABE has a right angle and 3 unequal sides, so therefore it can be classified as a right triangle.

b. In ∆BEC, side BE = 7

Side CE = FE + FC = 5 + 2 = 7

This means that ∆BEC has tow equal sides. Therefore, ∆BEC is classified as an isosceles triangle.

c. ∆DEF has 3 equal sides. Therefore it is classified as an equilateral triangle.

d. ∆CDF has 3 unequal sides. Therefore, it is a scalene triangle.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
