What else can I help you with?
Which type of triangle has three congruent sides and what do each measure?
An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
What is a polygon with all sides have the same measure all angles have the same measure with three sides?
Triangle
How do you state if the three numbers can be measure of the sides of a triangle?
state if the three numbers can be measures of the sides of a triangle. show your work 1- 15,12,9
A triangle in which at least two of the three sides and angles are equal in measure is?
Isosceles Triangle
What is the side of a triangle to which the altitude is dropped at a 90 degree angle?
Every one of the three sides.
What is a polygon all of its sides have the same measure and all of the angles have the same measure it has three sides?
It is an equilateral triangle
What is a polygon with all sides with the same measure and all the angles the same measure that has three sides?
An equilateral triangle
How is a equaliteral triangle different than a scalene triangle?
All three sides (and therefore angles) in an equilateral triangle are the same measure. All three sides (and therefore angles) in a scalene triangle are different.
How do you find angle in a triangle when the sides and altitude are givenin trigonometry?
Suppose you are given the three sides of a triangle and the altitude from the apex to the base. The altitude divides the triangle into two right-angled triangles and the arcsine function can be used to determine the two base angles. Subtracting their sum from 180 gives the third angle.
How and by its angles do you describe each triangle by its sides?
Equilateral triangle-All three sides are equal-All three angles measure 60 degreesIsosceles Triangle-Two equal sides-Two equal anglesScalene Triangle-Three unequal sides-No rule for angles (just have to add up to 180 degrees)
When does a polygon have three sides all of the same measure?
It's an equilateral triangle.
How to measure a triangles perimeter?
You find the three sides of the triangle, and assure that they are all in the same unit, and then add the sides together to find the perimeter of the triangle.
