How many degrees does an isosceles triangle have?
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.
What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
What degrees are each corner in an isosceles triangle?
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 angles of a triangle each measure 70 degrees what is the triangle is described as?
That's an isosceles triangle.
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.
What degree angles has an isosceles triangle?
a isosceles has 180 degrees
What is the degrees of an isosceles triangle?
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.
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
Which triangle is not an isosceles triangle?
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle with angles of size (90, 45, 45) degrees is a right angled isosceles triangle.
What angles does an isosceles triangle have?
-- In any triangle, the three inside angles always add up to 180 degrees. -- In an isosceles triangle, two of the three inside angles are equal.
How many degrees does an isosceles triangle have?
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.
What type of triangle has angles of 75 75 and 30 degrees?
An isosceles triangle has angles of 75, 75 and 30 degrees.
How many angles are there in an isosceles triangle?
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.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.
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.
Is is possible for an isosceles triangle to be an acute triangle?
Yes, but a triangle is acute only if all three of its angles are acute (< 90o).An isosceles triangle can be an acute triangle, but it doesn't have to be.An acute triangle can be an isosceles triangle, but it doesn't have to be.That depends on the sizes of its angle because an isosceles triangle has 2 equal sides and 2 equal angles which could be 70 degrees, 70 degrees and 40 degrees which are all acute angles that add up to 180 degrees.
A right isosceles triangle has?
two angles of 45 degrees
