Yes
The sides of a triangle add up to the perimeter.
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
Unless it is a right isosceles triangle, a normal right triangle has no pairs of equal sides.
3, 4 and 5
Yes
This is a right angle triangle.
Any triangle has three sides, whether it is a right triangle or not.
We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
The sides of a triangle add up to the perimeter.
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
right triangle and equilateral triangle both have 3 sides
An equilateral triangle has three equal sides. The angles of an equilateral triangle measure 60 degrees each, but the sides can be any length.
Unless it is a right isosceles triangle, a normal right triangle has no pairs of equal sides.
It is the right angle triangle which has 3 sides whereas all quadrilaterals have 4 sides.
with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle
