All triangles have 3 interior angles that add up to 180 degrees and are classified according to the size of their angles as follows:-
Right angle triangle: One 90 degree angle and 2 acute angles
Isosceles triangle: Two equal angles and another angle
Equilateral triangle: Three equal angles each measuring 60 degees
Obtuse triangle: One obtuse angle and 2 acute angles
Scalene triangle: Three acute angles of different sizes
Equilateral, isosceles, scalene and right angle triangles.
for two similar triangles , their corresponding angles are equal.
Classifying triangles is a great skill to know.Acute Triangles: These are triangles with measures lessthan 90 degrees.Obtuse Triangles: Any triangle with measures greater than 90 Degrees.Right Triangle: Any triangle with a Right Angle (exactly 90 degrees)
As many as you like but they will all be scalene triangles
Yes - in the case of triangles in Euclidian geometry. That is, basically triangles in a plane.
they would be congruent triangles!
Congruent Triangles have the same angles and side length measures
No only obtuse triangles have a measure over 90 degrees:)
Triangles are congruent if the lengths of their corresponding sides as well as the measures of their corresponding angles are the same.
All triangles that are not right triangles.
No, I learned that in 6th grade
Right triangles.
