1. ∠1 ≅ ∠3 1. given
∠1 and ∠6 are supplementary angles
∠3, ∠4, and ∠5 are supplementary angles
2. m∠1 = m∠3 2. definition of congruency
3. m∠1 + m∠6 = 180° 3. definition of supplementary angles
m∠3 + m∠4 + m∠5 = 180°
4. m∠3 + m∠4 + m∠5 = m∠1 + m∠6 4. transitive property
5. m∠3 + m∠4 + m∠5 = m∠3 + m∠6 5. substitution property
6. m∠4 + m∠5 = m∠6 6. subtraction property of equality

Answer:
The perimeter of the isosceles triangle is 32 centimeters
Step-by-step explanation:
<em>The perimeter of any figure is </em><em>the sum of the lengths of outline sides</em>
Let us use this fact to solve our question
∵ The perimeter of the triangle is the sum of the lengths of its 3 sides
∵ The triangle is an isosceles triangle
∵ The length of each two equal sides is 12 centimeters
∵ The length of the third side is 8 centimeters
→ Add the lengths of the 3 sides
∴ The perimeter of the triangle = 12 + 12 + 8
∴ The perimeter of the triangle = 32 centimeters
∴ The perimeter of the isosceles triangle is 32 centimeters
Ouch, kinda crippled w/o answer choices.
