In an isosceles triangle, two of the interior angles have the same number of degrees. This is because an isosceles triangle has two sides of equal length, which means the two base angles (the angles opposite those equal sides) are congruent. The third angle, called the apex angle, can be different from the base angles unless the triangle is also equilateral.
An isosceles triangle has interior angles of 180 degrees and exterior angles of 360 degrees
There are 3 angles in an isosceles triangle and 2 of them are equal in size. The 3 interior angles add up to 180 degrees.
The 3 interior angles of an isosceles triangle add up to 180 degrees and 2 of the angles are equal in size
An isosceles triangle has 3 interior angles that add up to 180 degrees two of which are equal in size.
An isosceles triangle has 3 sides of which 2 of them are equal in lengths with 3 interior angles of which 2 of them are equal in size and its 3 interior angles add up to 180 degrees.
An isosceles triangle has 3 interior angles that add up to 180 degrees, and 2 of its angles are equal and two of its sides are equal.
An isosceles triangle has interior angles of 180 degrees and exterior angles of 360 degrees
There are 3 angles in an isosceles triangle and 2 of them are equal in size. The 3 interior angles add up to 180 degrees.
The three interior angles measure 45, 45 and 90 degrees.
The 3 interior angles of an isosceles triangle add up to 180 degrees and 2 of the angles are equal in size
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
An isosceles triangle has 3 interior angles that add up to 180 degrees two of which are equal in size.
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.
An isosceles triangle has 3 sides of which 2 of them are equal in lengths with 3 interior angles of which 2 of them are equal in size and its 3 interior angles add up to 180 degrees.
The interior angles of an isosceles triangle total 180 degrees
An isosceles triangle has two equal angles and one different angle. The sum of the angles in any triangle is always 180 degrees. Therefore, the two equal angles in an isosceles triangle must add up to 180 degrees minus the different angle. So, each of the two equal angles in an isosceles triangle measures (180 - x) / 2 degrees.
Two and the three interior angles add up to 180 degrees
