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.

What is the total angle measure of isosceles triangle?
The sum of all three interior angles of any triangle, isosceles or not, is 180 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.
Why does the acute angles in an isosceles right triangle always measures 45 degrees?
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.
How many degrees are the angles of the base if the first angle 70 degrees?
If it's an isosceles triangle and the apex angle is 70 degrees then the base angles will each measure 55 degrees
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42?
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
What are the angle measurements for an isosceles right triangle?
An isosceles triangle has two sides and angles that are equal, causing it to have exactly a line of symmetry through it. A right triangle has one angle that is 90 degrees. An isosceles right triangle will always have one angle that is 90 degrees, while the other two angles will be 45 degrees.
What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
When a square is divided by a diagnal is an isosceles acute triangle is form?
A right angle isosceles triangle is then formed which will have two 45 degrees angles and one 90 degrees angle.
What is the angle that is not congruent to the base angles of an isosceles triangle?
The sum of the internal angles of a triangle is 180 degrees. If you know the size of the angles at the base of an isosceles triangle, the final angle can be found by subtracting the size of the two known angles from 180.
Does an isosceles triangle have a angle greater than 90?
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees. You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.
What is the maximum vertex angle in an isosceles triangle?
an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
An angle not congruent to the base angles of an isosceles triangle?
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
What is right angle triangle and isoceles triangle?
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
Does isosceles triangle have apex?
Yes an isosceles triangle has an apex angle and 2 equal base angles. The 3 angles add up to 180 degrees.
Can a triangle be does obtuse an isosceles?
An isosceles triangle can have an obtuse angle and two equal acute angles in which all 3 angles add up to 180 degrees.
Can a right triangle be isosceles?
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
What is the measure of the base angles of an isosceles triangle whose vertex angle has a measure of 50 degrees?
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
