What kind of triangle has 2 equal side lengths?
An isoceles triangle has 2 congruent sides of equal length, and one of a different length.(If all three side lengths are the same, you have an equilateral triangle, which is also equiangular, each angle 60°).
Are angles measured by their side lengths?
No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
Name of a triangle that has 2 equal length and one not equal length?
A triangle with 2 equal side lengths is called an isosceles triangle.
How many triangles have the side lengths 7in 7in 7in?
There is only one triangle with these side lengths. It is an equilateral triangle, where all three sides have the same length.
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 are the measurements for a scaline triangle?
A scalene triangle is simply a triangle where all of its sides are different lengths. One example of the side lengths of a scalene triangle are: 5cm, 6cm and 7cm
How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
Can the following side lengths form a triangle 3 8 3?
Yes, an isosceles triangle with two size lengths of 3 and one of 8 :)
If the square of the length of the longest side of a triangle is greater than the sum of the squares of the lengths of the other two sides of what kind of triangle?
It would be an obtuse triangle with one angle being greater than 90 degrees.

What is the formula for perimeter of a right triangle when one side is missing?
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
How do you work out the lengths of each side of an equilateral triangle?
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
What kind of triangle has 2 sides the same side and one side different?
An isoscles triangle
