A right triangle is a triangle that has one 90 degree angle, and 2 other angles.
Some special ones are 45-45-90, and 30-60-90.
The sum of the angles in a triangle will always = 180 degrees.
Since we know a triangle has 3 angles, and in particular, a right triangle has a 90 degree angle. We can say 180 degrees - 90 degrees = the other 2 angles.
Add the other 2 angles in your triangle. Usually one is given as 90 degrees, or has a small square mark in the corner of the triangle to indicate that it is a right triangle.
Once you add the other 2 angles, see if they add up to 90 degrees.
If they do, you have a right triangle.
If they do not, you either do not have a right triangle OR your triangle is broken and all 3 angles do not add up to 180 degrees.

How could you determine if a set of three numbers defines a right triangle?
If they are a Pythagorean triple then they will form a right angle triangle
What type of triangle has three equal sides and three equal angles?
A triangle with three equal sides and three equal angles is called an equilateral triangle.
How do you make a triangle with 3 right angles?
A triangle cannot have more than one right angle, which measures 90o. The sum of all three angles in a triangle must equal 180o.
What is the difference between an equilateral triangle and an acute triangle?
An acute triangle leans to the right but an equilateral triangle is wide and straight. An acute angle has three inside angles all of which are smaller than 90 degrees, which adds up to 180 degrees of course, and the sides are not necessarily equal. An equilateral triangle has three sides which are equal and each inside angle = 60 degrees (that is all three of them are the same angle automatically). Sides are equal or angles are equal = equilateral triangle.
What is a triangle with 3 equal sides?
A triangle with 3 equal sides also must have three equal angles; this is called an equilateral triangle.
How do you determine which numbers could respresent sides of a right triangle?
Pick three numbers. If the square of the largest number is equal to the sum of the squares of the other two, then the three numbers could represent the sides of a right triangle.
How do you find a right triangle when you have three numbers?
Three numbers may or may not define a right triangle. Also, the answer will depend on whether the three numbers are the lengths of sides or the measures of angles.
What do you call a triangle that has no equal sides?
a 'SCALENE' triangle. ; No equal sides, and no equal angles. An ISOSCELES triangle has two equal sides and two equal angles. An EQUILATERAL tringle has three equal sides and three equal angles all at 60 degrees. A RIGHT ANGLED triangle has one right angle (90 degrees) in it.
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
Is a polygon with only three equal length sides always a right triangle?
It is NEVER a right triangle. It is always EQUILATERAL.
How many sides does a right angle triangle have?
It has 2 equal sides of right triangle.
Does a right angle triangle have equal sides?
No, all three sides of a right angle triangle cannot be equal. In a right angled triangle, the side opposite the right angle - the hypotenuse - will always be the longest side of the triangle. The remaining two sides may be equal to each other, but they don't have to be.
How could you determine if a set of three numbers defines a right triangle?
If they are a Pythagorean triple then they will form a right angle triangle
What type of triangle has three equal sides and three equal angles?
A triangle with three equal sides and three equal angles is called an equilateral triangle.
What polygon has no right angles and three equal sides?
An equalateral triangle
Has a scalene any right angles?
A scalene triangle is a triangle in which all the sides are of the same length, and all three angles are equal i.e. all three angles are equal to 600. Therefore a scalene triangle cannot have a right angle.
What kind of triangle has three equal sides and three equal angles?
A triangle that has three equal sides, and therefore three equal angles, is called an equilateral triangle.
