The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
An isosceles triangle can have a 90 degree angle, but doesn't necessarily. Similarly, a right triangle can be an isosceles triangle, but isn't necessarily.
No.
An isosceles obtuse triangle is a triangle with 1 obtuse angle and only 2 congruent sides.
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
The angle sum of any triangle is 180 degrees. It does not matter whether it is equilateral, isosceles or scalene, nor whether it is acute angled, right angled or obtuse angled (or any permitted combination).
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
An isosceles triangle may have a right angle, but a right angle is not a requirement of all isosceles triangles.
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.
In an isosceles triangle, the two angles at the bottom are equal. Subtract the sum of the two bottom angles from 180 to find how many degrees are in the top angle.
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.
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
An isosceles triangle can have a 90 degree angle, but doesn't necessarily. Similarly, a right triangle can be an isosceles triangle, but isn't necessarily.
For an isosceles triangle with vertex 46 degrees, the sum of the remaining two base angles is 180-46 = 134 degrees. Base angles are equal because it's isosceles, so each angle is half of their sum. 134/2 = 67 degrees. Thus, any isosceles trapezoid formed inside that isosceles triangle by drawing parallel lines to the triangle's base, will have base angle measures of 67 degrees, which are triangle's base angles.
there are three angles on an isosceles triangle
