What are characteristics of an isosceles?
A three sided polygon in which two sides are equal in length and two angles are equal in size. Two sides have the same length as each other. The other side may be shorter or longer in length than the other two sides.
What are the characteristics of an isosceles triangle?
Two sides have the same length as each other. The other side may be shorter or longer in length than the other two sides.
What are the requirements for the side lenghts of a triangle?
The length of each side is longer than the sum of the lengths of the other two sides.
What is Side-Side-Side postulate?
The Side-Side-Side (SSS) postulate states that if all three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent. In other words, if the lengths of the three sides of one triangle are equal to the lengths of the corresponding three sides of another triangle, then the two triangles are congruent.
What is the triangle inequality theory?
The triangle inequality theory means that the two short sides of a triangle has to be greater when added up,than the longer side. Ex) 2+2=4(for the two smaller sides) The longer side being 2,so the other two sides are greater.Then can also it be a trinagle.

What is true about the lengths of the three sides of a triangle?
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.

How do you find the lengths of the three sides if one side is 9 inches longer than the shortest?
First, it is necessary to know three sides of what - most likely a triangle but the question does not say so. If a triangle, the difference of two sides is not sufficient to determine the lengths of the three sides.
Why do certain side lengths not make a triangle?
Because the 2 smaller sides must be longer than the longest side. In other words, a+b>c a and b are the shortest sides and c is the longest side.
What is the length of the third side of a triangle that has side of 22 and the other of 5?
The property you can use here is that no side can be longer than the sum of the other three sides. Thus, the third side must be somewhere between 22 - 5, and 22 + 5 (the "between", in this case, is not inclusive, i.e., it doesn't include the endpoints).
What is Side-Side-Side postulate?
The Side-Side-Side (SSS) postulate states that if all three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent. In other words, if the lengths of the three sides of one triangle are equal to the lengths of the corresponding three sides of another triangle, then the two triangles are congruent.
Which side of a rectangle is the length?
Either of the longer and shorter sides, but the length is usually the longer side and width is usually the shorter side.
What is the triangle inequality?

Is angle-angle-side a correct property of concurrency of triangles?
As long as the sides correspond then yes. The other three are: Side-Side-Side Side-Angle-Side - the angle *MUST* be between the two sides Right angle-Hypotenuse-Side
How is a rectangle and trapezoid similar?
They both have four straight sides, and at least one of the sides is a different length from the other three (in a rectangle, opposite sides are the same length, and has for right-angled corners. In a regular trapezoid, the bottom side is usually the longest, the two angled sides are the same length, and the top might be the same length as the sides, longer, or shorter. as long as it isn't the same as the first (bottom) side).
