That's a triangle in which all three sides have three different lengths.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
-- Every triangle, no matter what its shape or size, has three angles inside it that add up to 180 degrees. -- Whyen you say "regular right angled triangle", I hope you don't mean that all three of its sides are the same length ... that's what "regular" usually means in geometry. It's impossible for a right triangle to have all of its sides equal.
130 in2 on all three sides if you add them all together....
All Triangles add up to 180 degrees, no matter if it is Right or Scalene or ANY TRIANGLE!! If it does not, it is not a triangle!
The sides don't add up to anything but the angles should add up to 180 degree to form right triangle or any other triangle.
add all of the sides together
Depending on the sizes who knows
right angled triangle does not have all equal sides
we should add all the sides of the triangle
It has 2 equal sides of right triangle.
There are four types of triangles. For an "equilateral triangle", all sides and angles have to be the same. For an "isosceles triangle", 2 of 3 sides and angles have to be the same. For a "scalene triangle", the "the same" rules don't apply. For a "right-angled triangle", one corner has to be a right angle (90 degrees.) For example in an equilateral triangle, as long as the sides are the same, they can add up to anything. However, angles are different. In any given triangle, the angles must add up to 180 degrees.
Add all sides together.
A right triangle.
A triangle with a right angle and different lengths for sides is a right, scalene triangle.
It is the right angle triangle which has 3 sides whereas all quadrilaterals have 4 sides.
If the triangle has a right angle in it then it's a right triangle.A right angle triangle has 3 sides and 3 interior angles of 90 degrees and two acute angles which all together add up to 180 degrees.
