What are the kinds of triangles according to angles?
right triangle. obtuse triangle. acute triangle
If triangle ABC is congruent to triangle bcd then triangles ABC and bcd are what kinds of triangles?
The 2 triangles can be of any type (e.g isosceles, equilateral, etc.), only they must be exactly the same if they are congruent, i.e one triangle must be an exact copy of the other one.
Kinds of triangle according to size?
30"x60" and 45"
What are kinds of triangle according to their side?
Equilateral, isosceles and scalene.
What are the kinds of triangle according the measure of angle?
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
What kinds of symmetry do an equilateral and an isosceles triangle have?
An equilateral triangle has six symmetries, and an isosceles triangle has two. An isosceles triangle has a single axis of symmetry, the perpendicular bisector of the non-congruent side. This is a reflection symmetry. An equilateral triangle has rotational symmetry as well as reflection symmetry. It is invariant under rotations by 120 degrees.
What are the kinds of triangle according to measure of sides?
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
What are the different kinds of angles and triangle according to size and its angles?
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
What are kinds of sets according to number of elements what are kinds of sets according to number of elements?
Finite, countably infinite and uncountably infinite.
What are the three kinds of triangles according to the no of sides?
All triangles have exactly three sides. If the number of sides were anything other than three there would not be a triangle - of any kind.
Kinds of triangle according to angles?
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees
What are the diff kinds of triangles?
One way of classifying triangles is by the number of congruent sides (angles). A triangle is equilateral if all its sides are equal. All its angles will also be equal. A triangle is isosceles if two of its sides are equal. The angles at the end of the third side will be equal to one another. A triangle is scalene if all three sides are of different length. In this case, all three angles will also be different.
