It is a right angled isosceles triangle.
It is an isosceles triangle. 45 + 45 + 90 = 180 degrees
No, a triangle with two congruent sides is not always a 45-45-90 triangle. Such a triangle is classified as an isosceles triangle, which can have various angles, including right angles, acute angles, or obtuse angles. A 45-45-90 triangle is a specific case of an isosceles right triangle, where the angles are precisely 45 degrees each. Thus, while all 45-45-90 triangles are isosceles, not all isosceles triangles are 45-45-90 triangles.
Left triangle.
That is a icocsles triangle.
No. The only requirement for a triangle to be a 45-45-90 triangle is for it to have at least two congruent sides/angles. The measure of the two congruent angles can be anything.
A triangle with a 90 and two 45 degree angles is an isosceles right angle triangle.
It is an isosceles triangle. 45 + 45 + 90 = 180 degrees
No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.
No, a triangle with two congruent sides is not always a 45-45-90 triangle. Such a triangle is classified as an isosceles triangle, which can have various angles, including right angles, acute angles, or obtuse angles. A 45-45-90 triangle is a specific case of an isosceles right triangle, where the angles are precisely 45 degrees each. Thus, while all 45-45-90 triangles are isosceles, not all isosceles triangles are 45-45-90 triangles.
The formula for a 45-45-90 triangle is that both of the legs are n. The hypotenuse is n√2
Left triangle.
Isosceles triangle
That is a icocsles triangle.
Yes
special triangles: 45-45-90 triangle and 30-60-90 triangle
No. The only requirement for a triangle to be a 45-45-90 triangle is for it to have at least two congruent sides/angles. The measure of the two congruent angles can be anything.
equilateral triangle has all angles of 60 degrees isosceles triangle has only two equal angles scalene triangle have no equal angles acute triangle has all angles less than 90 degrees right angle triangle has one angle of 90 degrees obtuse triangle has one angle greater than 90 degrees right isosceles triangle has 90, 45, 45 degree angles assuming two angles are the same: acute isosceles triangle can range from <90,>45,>45 down to >0,<90,<90 obtuse isosceles triangle can range from >90,<45,<45 up to <180,>0,>0
