What is A shape with three sides called?
A shape with three sides is called a triangle: 3 equal sides = equilateral 2 sides same length = isosceles 1 right angle = right-angled triangle
What shape has exactly 3 horizontal sides?
It could possibly be a triangle depending on its base
How do you find the length of a side in a triangle that is not a right triangle?
Use either the Sine or Cosine rules depending on the information you know about the triangle.
What is the name of the side opposite the right angle in a right triangle called?
the opposite (i know kinda obvious)Improved Answer:-The hypotenuse
A right triangle has 28 degrees angle what are the measures of the other angles?
The sum of the internal angles of a triangle is 180 degrees. Since you know this is a right-angled triangle, you know that one side is 90 degrees. If the other angle is 28 degrees, then you know that the remaining angle must be 180 - 90 - 28 = 62 degrees.
How do you know when its a right triangle?
It will have an L shape flipped around at the corner. or you can use a protractor or type in google images 'right angle triangle' they will have an L shape at the corner of the right angled triangle.
What shape has three sides that are not equal but have a right angle?
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
What is A shape with three sides called?
A shape with three sides is called a triangle: 3 equal sides = equilateral 2 sides same length = isosceles 1 right angle = right-angled triangle
A triangle with one right angle?
A triangle with 1 right angle is a right angle triangle.
How do you know if a triangle is a right triangle?
If it has one 90 degree angle then it is a right triangle.
What shape has 3 horizontal sides?
Triangle
What shape is a square and a triangle?
A house i don't really know
How do you know if a triangle is a right triangle using the pythagorean therom -?
Pythagoras' theorem states that for any right angle triangle the square of its hypotenuse is equal to the sum of its squared sides as in the following formula:- a squared + b squared = c squared whereas a and b are the sides of the triangle with c being its hypotenuse
What do you call A triangle with a 90 degrees angle?
Any triangle with a 90 degree angle is called a right triangle.
How do you know if a triangle is a right triangle by it's sides?
C2=a2+b2
How do you use pythagaoras theorem?

How do you know when a triangle is 90 degrees?
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
