What is a3 sided polygon with 2 sides and 2 equal angles?
Right triangle. Two angles are 45 degrees, and the third angle is 90 degrees. Two sides are equal.
What are the characteristics of a right isosceles triangle?
It has 3 sides and 3 interior angles that add up to 180 degrees It has 2 equal sides: It has 2 equal 45 degree angles It has one right angle of 90 degrees
Is there any such thing as an Equilateral right triangle?
No because an equilateral triangles has 3 equal sides and 3 equal angles of 60 degrees. But there is such a thing as an isosceles right angle triangle which has 2 equal sides and a 90 degree angle with two equal angles of 45 degrees.
What does all the triangles look like and what type of triangle are they?
There are infinitely many types of triangles, and they can be classified according to their angles or sides (or both). Equilateral (equiangular triangles): All sides equal, all angles 60 degrees. Obtuse angled isosceles triangles: Two sides equal; one angle > 90deg. Right angled isosceles triangles: Two sides equal; angles of 90, 45, 45 degrees. Other isosceles triangle: Two sides equal; angles of 180-2x, x, x degrees. Obtuse angled scalene triangles: All sides unequal, one angle > 90 degrees. Right angled scalene triangles: All sides unequal, one angle = 90 degrees. Acute angled scalene triangles: All sides unequal, all angles < 90 degrees.
What is the vertex angle of isosceles right triangle?
An isosceles triangle has two equal sides, and if one of the angles is 90 degrees, than the other two have to be equal. A triangle's angles always add up to 180 degrees, so the other two have to be 45 degrees.
What is a3 sided polygon with 2 sides and 2 equal angles?
Right triangle. Two angles are 45 degrees, and the third angle is 90 degrees. Two sides are equal.
What are three attributes of a square?
The sides are equal The angle between adjacent sides is 90 degrees There are two diagonals The diagonals are equal in length The diagonals make 90 degrees with each other The diagonals make 45 degrees with the sides
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.

What is true about a isosceles right triangle?
It has two equal sides and two equal 45 degree angles as well as a right angle of 90 degrees.
What is the length of the equal sides of an isoceles triangle were the two equal angles are 45 degrees?
This question is not possible to answer. You cannot determine the length of the sides with just the degree of two angles and the type of triangle.
What is the missing angle of a quadrilateral with a 135-degree angle?
If it is a 4-sided parallelogram, then its interior angles are 135, 135, 45 and 45 degrees because opposite angles are equal and the 4 angles add up to 360 degrees.
How does an isosceles triangle look when it is a right triangle?
An isosceles triangle will have equal sides and 2 equal angles of 45 degrees plus a 90 degree angle.

Does tan 45 degrees and sin 45 degrees equal trig values?
They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
If the exterior angle of a regular polygon is 45 degrees how many sides does it have?
360/45 = 8 sides.
