No. An isosceles right triangle has the measures of 90, 45, and 45. Isosceles means that two sides are congruent. Hope this helps :)
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
The angles will be 90, 45 and 45 degrees
An equilateral triangle is a special isosceles triangle in which all three sides are congruent. Equilateral triangles are also equiangular, which means all three angles are congruent. The measure of each angle is 60 degrees.
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
Isosceles right angled triangle, as the remaining angle must be 90o.
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.
It is an isosceles triangle and its other two angles each measures 35 degrees
Isosceles Triangle Isosceles TriangleIsosceles triangles have at least 2 congruent sides, and equilateral triangles have all 3 sides equal. A scalene triangle has no congruent sides or angles. All triangles have 180 degrees total.An equilateral triangle has three congruent sides and an isosceles triangle has two congruent sides.
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.
Isosceles triangles usually have two congruent sides, but the rule is that they actually have at least two. That means that they can also have a third congruent side. That means they are both equilateral and isosceles*, which I personally think is way too confusing, but that's how it works.Example: A triangle has angles of 60 degrees, 60 degrees, and 60 degrees. It is both isosceles and equilateral.*I think that equilateral triangles are actually a type of isosceles triangle, so that if you're asked on a math test, for example, whether a triangle is scalene, isosceles, or equilateral, you'd say equilateral.No, Isosceles is two equal sides, although an equilateral triangle CAN be an isosceles triangle. And Angles of an isosceles triangle are not known (given) - simply two equal sides.Three, like every other triangle.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees. Equilateral triangles have 3 congruent sides. Isosceles triangles have 2 congruent sides. A right angle triangle can have 2 congruent sides if its interior angles are 90, 45, 45 degrees. A scalene or an obtuse triangle has no congruent sides.
The angles will be 90, 45 and 45 degrees
No, since an equilateral triangle has three congruent angles of 60 degrees, and a right triangle must have an angle of 90 degrees. However, a right triangle may be an isosceles triangle.
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
When it has a 90 degree angle and 2 equal angles of 45 degrees
