Answer:

An isosceles triangle

Step-by-step explanation:

After solving for all the angles In the Triangle ABC,

Angle B = 80

Angle C = 50

Angle A = 50

An isosceles triangle is a triangle that the base angles are equal.

In the image the triangle has two equal angles.

Answer:

ISCOCELES TRIANGLE

Step-by-step explanation:

<BAC is alternate to <ACD and <ABC is alternate to <BCE

So, <BAC = <ACD = 50° and <BCE = <ABC = 80°

<ACD + <ACB +<BCE =180 (sum of angles in a straight line)

50° + <ACB + 80 = 180

<ACB = 180-(80+50)

<ACB = 180 - 130 = 50°

You can see that the base angles <BAC and <ACB are equal(<BAC =50° and <ACB = 50°), so the triangle is an Iscoceles triangle.
