Since the vertex angle is 64⁰, the base angle is 58⁰, (180⁰ - 64⁰ )/2.
Using the Law of Sines we have
side length/sin 58⁰ = 3 cm/sin 64⁰ (multiply by sin 58⁰ to both sides)
side length = (3 cm)(sin 58⁰)/sin 64⁰ ≈ 2.8 cm
Thus, the congruent sides of the given isosceles triangle have a length of 2.8 cm.
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
101 degrees :p
In an isosceles right angled triangle,1 angle is 90 degrees and the other two are equal ,each is 45 degrees
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.
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
because an isosceles triangle or any kind of triangle is 180 degrees.
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 isosceles has 180 degrees
There is 180 degrees in every triangle.
The right isosceles triangle has 180 degrees as all triangles do
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.
a right triangle
101 degrees :p
It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled 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.
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.
