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.
Explain the sum of the numbers in each row in Pascal's triangle?
the horizontal sums doubles each time the sum of row 1 = 1 row 2= 2 row 3 = 4 row 4 = 8 row 5 = 16 etc etc.......... the horizontal sums doubles each time the sum of row 1 = 1 row 2= 2 row 3 = 4 row 4 = 8 row 5 = 16 etc etc..........
Explain why triangles have no diagonals?
Because the lines between each vertice of the figure are already drawn.
Explain why all equilateral triangles must be similar?
Each has 3 interior angles of 60 degrees Each has 3 equal sides in length Similar triangles are defined as those that have corresponding angles of the same measure.
How many triangles meet at each edge of an icosahedron?
Two triangles meet at each edge.
What does each letter mean in the word PASCAL?
PASCAL is not an acronym. It was named for Blaise Pascal, a French mathematician who was a pioneer in computer development.
How much is generated each year?
How much what is generated each year
How would you prove triangles are congruent?
You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.
Can all isosceles triangles be equilateral triangles?
No, not all isoceles triangles can be equilateral triangles because an equilateral triangle has sides that are all equal to each other and an isoceles triangle has only two sides that are equal to each other.
What do regular triangles look like?
all regular triangles has 60degreeson each angles.
In pascal triangle each row is bounded by?
1
How are triangles alike?
Triangles are alike or similar to each other when their sides are proportionate and have the same angles.
Explain why you can not use angle angle angle to prove two triangles are congruent?
Knowing that three angles are congruent only proves that two triangles are similar. Consider, for example, two equilateral triangles, one with sides of length 5 and the other of lengths ten. Both have three angles of 60 degrees each, but they are not congruent because their sides are not of the same length.
What is the fraction value of a medium triangle in a square?
If the small triangles are worth 1, determine the value of the other Tangram pieces.Be sure to explain your reasoning.More Challenging Version:Find the fractional part each tangram piece is of the whole (all 7 pieces).Now, suppose the large triangles are worth 1/2, determine the value of the other Tangram pieces.Be sure to explain your reasoning.
