These are the degrees of each angle. It is a right triangle, and it also is an isosceles triangle.
you need the apex angle, call it n. Each base angle is one-half of (180 - n)
An isosceles triangle has two equal angles. All the angles of a triangle add up to 180º There can not be another angle with 90º as that would mean the last angle was 0º, so the other two angles must be 45º each.
The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.
40 degrees each
55 degrees because there are 180 degrees in a triangle
90° 45° 45°
In an isosceles right angled triangle,1 angle is 90 degrees and the other two are equal ,each is 45 degrees
The measure of each base angle in an isosceles triangle can be calculated by dividing the total angle sum by the number of base angles, i.e., (180 - vertex angle) / 2. In this case, each base angle of the isosceles triangle would measure (180 - 38) / 2 = 71 degrees.
The base angles of an isosceles triangle are the two angles that are equal to each other. They can be between 89.999...o and 0.000000..01o.
These are the degrees of each angle. It is a right triangle, and it also is an isosceles triangle.
70
The sum of the interior angles of a triangle is 180o. In an isosceles triangle two of the angles are the same, say x. The third angle is then 180o-2x.
If two angle bisectors of a triangle are congruent, then the triangle is isosceles. This is because the angle bisectors of a triangle are concurrent and the angle bisectors of a triangle that are congruent divide the opposite sides of the triangle into two equal segments. So if two angle bisectors are congruent, the sides opposite those angles are also equal, making the triangle isosceles.
Yes normally, unless it is a right angle isosceles triangle which will have angles of 90, 45 and 45 degrees.
