A right triangle is a triangle that has how many degrees?
in plane geometry: all triangles have 3 angles which add up to 180 degrees, in a right triangle one of those 3 angles is 90 degrees.
Picture of a triangle with all angles less than a right angle?
It is a scalene triangle which has 3 different interior acute angles
How many equal sides and right angles does an equilateral triangle have?
An equilateral triangle, has 3 equal sides and 3 equal angles. However, in a regular equilateral triangles, none of these angles are right angles (90 degrees), they are all 60 degrees.
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.
How can you tell if three numbers equal a right triangle?
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.
