Finding measurements of triangle only given one angle measurement?
Not possible. There are an infinite number of triangles that all have that same one angle in them.
Which triangles have a right angle?
Right angled triangles!
What are triangles that share a common angle?
Equilateral triangles
What triangles have a 45 degree angle?
acute 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.
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 the sum of the angle measurement of a decagon?
Pick a point around the center of the polygon. Join each vertex to this point. You will now have 10 triangles. The total angle of these 10 triangles is 10x180 degrees. Now you need to subtract the angles of the ten triangles at the center (which is 360 degrees). Therefore total internal angles is (10x180)-360 = 1800-360 which is 1440 degrees.
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
Why do you have to divide by 2 for a triangles base and height?
Area is measured in squared units and a triangle can be shown as the equivalent of half a square. This is why the triangles base and height is divided by 2. Proof for triangle as the equivalent of half a square: Internal angle measurement of a triangle is 180 degrees. Internal angle measurement of a square is 360 degrees. Note: the above proof may not be true pertaining to non-Euclidean geometry.
What are the measurements of each angle in a regular octagon?
If you cut a regular octagon into triangles, it would be 6 triangles. the measurement of all the angles in a triangle added up are 180 degress multiply 6x180=1080 the measurement of all the angles in a octagon added up are 1080 degress there are 8 angles in a octagon. divide 1080 by 8=135 135 degress in each angle in a regular octagon
What triangles do builders most often use?
Right angle triangles.
