How many lines of symmetry does a right triangle have?
Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
Why can some isosceles triangles be ringt angle triangles?
An isosceles triangle only requires that two of its inside angles be equal to eachother. Therefore, a right angle triangle (90 degree inside angle) with two 45 degree inside angles on the the two other corners would be considered an isoceles triangle. However, this would be the ONLY right angle triangle that would be considered an isoceles triangle since all inside angles must add up to 180 (90+45+45=180).
Two lines are perpendicular if they cross at 45 degree angles?
Two lines are perpendicular if they cross at 90 degree angles.
What is meant when they say put at a 45 degree angle?
A 90 degree angle can be bisected into two 45 degree angles with a compass and straight edge The diagonals of a square bisect their opposite corners into 45 degree angles
What are the two complementary angles?
There is an infinite number of complementary angles. Complementary angles are all angles that add up to 90 degrees, such as two 45 degree angles.
Do all isosceles right triangles have two 45 degree angles?
Yes as well as a 90 degree angle
Which triangle has a 45 degree angle?
There are an infinite number of different triangles, with all different shapes and sizes, that all have 45-degree angles. If it happens to be a right triangle, then it has two 45-degree angles, and it's an isosceles right triangle.

Two angles are congruent and complementary.What are the measures of the angles?
it is 45 degree

If a right angle is bisected what are th resulting angles?
acute 45 degree angles
Two angles that can be trisected with a straight edge and compass are what degrees?
45 degree and a 90 degree angles
What does a right triangle angles measure?
They have one 90 degree angle and two 45 degree angles
How many unique triangles can be made when one angle measures 90 and another is half that measure?
It will be in the form of an isosceles right angle triangle when it has a 90 and two 45 degree angles
Can two angles be equal if they are complimentary?
Yes- both will be 45-degree angles.
Two lines are perpendicular if they cross at 45 degree angles?
Two lines are perpendicular if they cross at 90 degree angles.
When a square is divided by a diagnal?
It is divided into two congruent triangles. Congruent means "the same size and shape" The triangles are right-angled with the other 2 angles each being 45 degrees. The sides opposite these 45 degree angles are two of the sides of the original square. If cut out, one triangle would fit exactly over the other one.
