Which triangles have a right angle?
Right angled triangles!
What triangles have a 45 degree angle?
acute triangles
What are triangles that share a common angle?
Equilateral triangles
Is angle angle angle a way to show that triangles are similar?
Yes, AAA is a way to show that triangles are similar. Note, however, that AAA is not a way to show that triangles are congruent.
What kind of triangles does the Pythagorean theorem work for?
All right-angles triangles. That is triangles that contain one angle at 90 degrees.
Is there such thing as a right obtuse angle?
No. Right triangles are triangles with one angle exactly 90°, and obtuse angles are triangles with exactly one angle that is greater than, but not equal to, 90°.
What is angle angle angle in gemotry?
AAA, or angle angle angle, is a postulate used to prove the similarities of two triangles. If there exists a correspondence between the vertices of two triangles such that the three angles of one triangle are congruent to the corresponding angles of the other triangle, then the triangles are similar. (AAA)
Which triangles have a right angle d a or c?
They are the triangles that contain a 90 degree angle and two acute angles
What are facts about right triangles?
The ratio of the length of the side opposite a given angle to the hypotenuse is the sine of that angle.The ratio of the length of the side adjacent to a given angle to the hypotenuse is the cosine of that angle.The ratio of the length of the side opposite a given angle to the side adjacent to that angle is the tangent of that angle.
What triangles do builders most often use?
Right angle triangles.
What are the classification of triangles?
Equilateral, isosceles, scalene and right angle triangles.
What kind of triangles relate to Pythagorean theorem?
Right-Angle triangles
