Does an isosceles triangle have a right angle?
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.
Does an isosceles triangle have right angles?
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.
What are 2 properties of an isosceles triangle?
-- An isosceles triangle has two equal sides. -- An isosceles triangle has two equal angles. -- An isosceles triangle has two equal interior-angle bisectors. -- The bisector of the vertex angle of an isosceles triangle is also the perpendicular bisector of the triangle's base.
Has an isosceles triangle have an obtuse angle?
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
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.
What is the name of a triangle with two equal sides?
It is an isosceles triangle -- of necessity there are two identical and mirrored angles.If the third side is also equal, it is an equilateral triangle.If there is also a right angle, the other two angles are 45 degrees and it is an isosceles right triangle.
Can a right triangle be an isosceles triangle?
Yes, a right triangle an be an isosceles triangle. The triangle will will have a 90 degree angle and two 45 degree angles. This is the only way a right angle triangle can also be an isosceles triangle.
What is the angle of an isosceles triangle?
The two angles that are not the isosceles vertex are equal.
If an angle bisector of an isosceles triangle yields two isosceles triangles what were the angle measures of the original triangle?
they would be congruent triangles!
Can isosceles triangles be right?
Yes, isosceles triangles can be right triangles. An isosceles triangle has at least two sides of equal length, and if one of the angles is a right angle (90 degrees), the triangle is classified as a right isosceles triangle. In this case, the two equal sides are the legs of the triangle, and the third side is the hypotenuse.
A triangle with two congruent sides and an angle of 104 degrees is?
A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
