Is 4: 9 equivalent to36: 72 use a tape diagram to find the answer

I'm not sure what you mean by "tape diagram" but you can use a proportion to check. Assume that 4/9 is equal to 36/72 for now. We'll use cross multiplication to show that it's actually false.

4/9 = 36/72

4*72 = 9*36 ... cross multiply

288 = 324 ... this is false

The last equation is false because we get two different values on either side, so the first equation must be false

So 4:9 is not the same as 36:72

answer: slight chance that it will happen

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
