acute angle = less than 90o & greater than 0o right angle = 90o obtuse angle = greater than 90o & less than 180o straight angle = 180o reflex angle = greater than 180o
Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. Classification by sides includes equilateral, isosceles, and scalene.
That all interior angles are equal in size.
No - if the lengths of the sides are all increased by a factor of 3, the angles remain unchanged. You just wind up with a "similar" triangle 3 times the size of the original. A quick counterexample would be to consider what would happen if the angles DID change. The sum of the angles in the original triangle should be 180°. If the angles in the new, larger triangle tripled in size, the sum of the angles in the bigger triangle would be 540° - but the sum of the angles of a triangle should always remain 180°.
Then the alternate angles created would be equal in size.
Yes. Similar figures are the same shape, but not necessarily the same size; their angles are equal.
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
equaladiral triangle: all sides are equal in size scalene triangle: all sides are different in size isosceles triangle: two sides are the same length in size
Angles that are less than 90 degrees are acute angles. Angles that are 90 degrees are right angles, and angles that are greater than 90 degrees are obtuse angles.
we identify it when it has measure ment in its vertex
right triangle. obtuse triangle. acute triangle
There are four different kinds of angles and they are:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 degrees
30"x60" and 45"
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
They have obtuse angles on each side.
ahahahaahhaahaha ahm,,,,,,, amvot unsa?
Right, obtuse acute, reflex and scalene angles.
Any size you like. here are no restrictions on the size of individual angles.
