How can you determine when two triangles are similar?
You determine the similarity of two triangles through the equality of each two relevant lines and the equality of each relevant two interior angels.
How many triangles can be formed in octagon using the vertices of the octagon as the vertices of triangle?
There are 48 triangles that can be formed because 6 triangles can be formed usin each point multiplied by 8.
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
What postulate or theorem verifies the congruence of triangles?
sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.
How do you divide 4 triangles in 3 equal groups?
You'd have to have fractional parts of triangles. Each group would have 1 and 1/3 triangle.
