no. if it contained two 90 degree angles it would have to have at least four sides.

Example of different kids of angles?
Acute angles (less than 90 degrees) Obtuse angles (greater than 90 degrees) Right angles ( equal to 90 degrees)
How do you find sin of angle?
The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.
What is the third angle of a right triangle if one of the angles measures Y?
If Y is the right angle then the third angle is indeterminate. Otherwise it is 90 - Y degrees.
What is the difference between the acute obtuse and reflex angles?
Acute angles are greater than 0 but less than 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees but less than 360 degrees
What is the complementary angle of 113 degree angle?
Two angles are complementary if they both add up to 90 degrees. This means that a complementary angle would have to be negative 23 degrees if the given angle is 113 (-23+113=90) . However I suspect that you are looking for the supplementary angle. Supplementary angles total 180 degrees. If so, the supplement would be 77 degrees.
Are the two acute angles of a right triangle complementary?
Yes. Compementary angles total 90 degrees. In a right angled triangle the right angle uses 90 of the 180 degrees in a triangle, leaving 90 degrees for the other two angles.
If two angles of a triangle each measure 45 degrees what is the third angle?
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
A right angles triangle, as one of the angles in the triangle is 90 degrees.
If one the angles of a right triangle is 30 degrees what are the other two angles?
Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==
What are the angles of a right isosceles triangle?
The two other angles are 45 degrees each. The three angles of every triangle always add up to 180 degrees. -- A right triangle is a triangle that has a right angle in it. -- A right angle is 90 degrees. -- That leaves 90 degrees for the other two angles in the right triangle. -- If it happens to be isosceles, then the other two angles are equal. -- Those must both be 45 degrees.
What are 3 angles in a right triangle?
All the angles of a triangle add up to 180 degrees. In a right triangle one of the angles must be 90 degrees and the other two can be any combination that adds to 90, such as 30 degrees and 60 degrees.
What of kind of angles are the other two angles of the triangle?
If it is an equilateral triangle all the angles would be 90 degrees or right angles
Is a right triangle a triangle with two right angles?
A right angle triangle has only 1 right angle of 90 degrees and two acute angles that add up to 90 degrees whereas the 3 angles add up to 180 degrees
What are the kinds of triangle acording to their angles?
equilateral triangle has all angles of 60 degrees isosceles triangle has only two equal angles scalene triangle have no equal angles acute triangle has all angles less than 90 degrees right angle triangle has one angle of 90 degrees obtuse triangle has one angle greater than 90 degrees right isosceles triangle has 90, 45, 45 degree angles assuming two angles are the same: acute isosceles triangle can range from <90,>45,>45 down to >0,<90,<90 obtuse isosceles triangle can range from >90,<45,<45 up to <180,>0,>0
Can you draw an obtuse triangle?
Yes, its a triangle that has one obtuse angle (an angle over 90 degrees) and two acute angles (angles that are les that 90 degrees).
Can a right triangle have two angles that measure 90 degrees?
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
What kind of triangle has one right angle and two acute angles?
A right angle has a 90-degree and in two acute angles.
