with a protractor. or if you don't have one, you can find it using the degrees you already have. The degrees in a triangle should always be 180. So, take the info you have, add it together, then subtract it from 180 (i.e 90+45=135. 180-135=45).

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.
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.
How do you find angles to a right triangle?
You cannot. The other angles of a right triangle can have any values between 0 and 90 degrees as long as the two of them sum to 90 degrees.
A right triangle is a triangle that has how degrees?
It has 180 degrees, but one angle of the triangle has to be 90 degrees
What are the angle classifications of a triangle?
The question "What are the classifications of a triangle" is answered elsewhere. The angles in a triangle can be either an obtuse >90 degrees, an acute <90 degrees, or a rectal = 90 degrees
A triangle with one angle over 90 degrees?
A triangle with one angle over 90 degrees is an obtuse triangle.
Kinds of triangle according to angles?
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees
What are 3 kinds of triangle according to angle?
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
What type of triangle has an angle that measures 20 degrees and and angle that measures 90 degrees?
Any triangle that has an angle measuring 90 degrees is a right triangle.
What triangle has 30 degrees 60 degrees and 90 degrees?
A right-angle triangle
Find the third angle of a right triangle if the measure of on of the angles is 68?
The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
