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
If a triangle has one 90 degree angle what are the other angles?
The other two angles can be any two that add up to 90 degrees.
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.
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.
Two angles are congruent and complementary.What are the measures of the angles?
it is 45 degree

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).
If a right angle is bisected what are th resulting angles?
acute 45 degree angles
What does a right triangle angles measure?
They have one 90 degree angle and two 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
Can two angles be equal if they are complimentary?
Yes- both will be 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
Two lines are perpendicular if they cross at 45 degree angles?
Two lines are perpendicular if they cross at 90 degree angles.
What triangles have a 45 degree angle?
acute triangles
