Step-by-step explanation:

The answers to number 1 for each triangle are solved exactly how they are written :).

The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.

Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.

Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.

A _____________ ratio in any proportional relationship.

Answers

Answer:

a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x

If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

Step-by-step explanation:

Proportions are the same ratios written in different forms. A proportional relationship is states that they are the same. For example, 1/2 and 6/12 have a proportional relationship, which means they are the same.
