What type of triangle has a angle that measures 20 degrees and 90 degrees?
The 3rd angle is 70 degrees which would form a right angle triangle.
What is a triangle with angles of 60 degrees and 30 degrees?
The third angle has to be 90 degrees so it would be a right angle triangle.
Why can't an obtuse triangle not have a right angle?
Because an obtuse angle is greater than 90 degrees by definition and a right angle is 90 degrees by definition, so an obtuse triangle would need to have both a right angle and an obtuse angle, which would exceed the number of degrees than a triangle can have, which is 180 degrees.
What type of triangle has an angle that measures 20 degrees and an angle that measures 90 degrees?
right triangle and the other angle would be 70 degrees. Hope I helped :)
Does a equilateral triangle have right angle?
Only right triangles have right angles. An equilateral triangle though can't have a right angle because all the angles in any type of triangle must add up to 180 degrees. For each angle to be equilateral, they must be 60 degrees, showing that there is no angle at 90 degrees in an equilateral triangle, which would signify that it would be right.
Can a triangle have to right angles if yes what would be the size of the third angle?
A right angle triangle can only have 1 right angle of 90 degrees and its 3 interior angles add up to 180 degrees
Why a triangle can not have more than one right angle?
The sum of the internal angles of a triangle (in 2-d) must be 180 degrees. If there are two right angles - of 90 degrees each - then the third angle would be 0 degrees! That would not be a triangle.
Can one angle in a right triangle measure 100 degrees?
No, because a triangle's angles can only measure up to 180 degrees. A right angle is 90 degrees, plus another 100 degree angle would be 190 degrees.
Does and acute has a right angle and two acute angles?
no an acute triangle does not have a right angle. if it had a right angle, it would be called a right triangle. to be an acute triangle, the triangle needs two angles that are smaller than 90 degrees.
If two of a triangle angles measure 42 degrees 48 degrees how would you classify that triangle?
acute , obtuse obtuse or right angle
What type of trangle has an angle that measures 20 and an angle that mearuses 90?
It is a right angle triangle and the 3rd angle would measure 70 degrees
Is there a right triangle in an equiangular triangle?
No there is not. A right triangle has to have an angle of 90 degrees. An equiangular triangle has 3 equal angles. If a right triangle was equiangular, it would be 90 times 3 equaling 270 degrees. There are only 180 degrees in a triangle.
