All triangles have 3 interior angles that add up to 180 degrees and they are:-
Right angle triangle: 90 degree angle and 2 acute angles
Obtuse triangle: An obtuse angle and 2 acute angles
Scalene triangle: 3 acute angles of different sizes
Isosceles triangle: 2 equal angles and another angle
Equilateral triangle: 3 equal angles that each measures 60 degrees
What else can I help you with?
What kind of triangles does the Pythagorean theorem work for?
All right-angles triangles. That is triangles that contain one angle at 90 degrees.
How do you prove triangles similar?
To prove that two or more triangles are similar, you must know either SSS, SAS, AAA or ASA. That is, Side-Side-Side, Side-Angle-Side, Angle-Angle-Angle or Angle-Side-Angle. If the sides are proportionate and the angles are equal in any of these four patterns, then the triangles are similar.
What is the type of congruence between the triangles shown?
side- angle- side
What are the three methods of proving triangles congruent?
SSS- side side side SAS- side angle side ASA- angle side angle There is also: AAS- angle angle side For right triangles: HL- hypotenuse leg
Are all 30-60-90 triangles isosceles?
No because 30-60-90 triangles are right angle triangles
What are the kinds of triangles according to measure of their sides and angles?
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
What triangles have a 45 degree angle?
acute triangles
What are triangles that share a common angle?
Equilateral triangles
Which triangles have a right angle?
Right angled 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 the classification of triangles?
Equilateral, isosceles, scalene and right angle triangles.
What triangles do builders most often use?
Right angle triangles.
What kind of triangles relate to Pythagorean theorem?
Right-Angle triangles
