How many triangles can be formed with 5 vertices?
10 triangles....
How many different triangles can be formed using three vertices of a hexagon as vertices of a triangle?
30, its a combination. C(6,3) because there are six vertices of a hexagon and three vertices of a triangle
What shape is formed using 5 congruent triangles and has 5 vertices 5 angles 5 sides?
pentagon
The figure formed by two straight lines meeting at a point?
The intersection of two lines is a point. If both lines are straight the figure of four separate triangles are formed. The type of triangles are dependent on the angle of the intersection.
How many triangles are formed by the diagonals from six vertices of a hexagon?
The three major diagonals in an ordinary hexagon do not intersect at the same point. Therefore, in such a hexagon, the diagonals form 111 triangles.
How many triangles can be formed in a 15 sided polygon when one of its vertices is joined to the other vertices?
13 triangles will be formed
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.
How many triangles can be formed with 5 vertices?
10 triangles....
Triangles formed by joining the vertices of a decagon?
Eight triangles.

How many triangles can be formed by using any three points as their vertices?
The answer depends on how many points there are and how many triplets are non-collinear.
Can six identical triangles can be formed by drawing two straight lines through an octagon's center point?
No.
Can a trapezoid be formed into a square and triangle?
Yes, Some can even be formed into a square and two triangles or a rectangle and one or two triangles. Just drop perpendicular(s) from the vertex (vertices) of the short side to the long side (that is to say, the two sides which are parallel). That will form one or two right triangles and a rectangle of some sort...could be a square--all squares are rectangles but not all rectangles are squares.
If all of the diagonals are drawn from a vertex of an octagon how many triangles are formed?
5 triangles are formed.
