Are two triangles with corresponding congruent angles congruent?
No, they are similar. They may be congruent, but they need not be.
What Angle bisector of a triangle?
An angle is formed by two rays with a common endpoint. The angle bisector is a ray or line segment that bisects the angle, creating two congruent angles. To construct an angle bisector you need a compass and straightedge. Bisectors are very important in identifying corresponding parts of similar triangles and in solving proofs.
How many short isosceles triangles are needed to build one great Icosahedron?
According to some definitions an icosahedron is considered a Platonic solid so that each of its faces is an equilateral triangle. You would, therefore need three coplanar isosceles triangles to make each face of the icosahedron. Since there are 20 faces in an icosahedron, you would need 60 such triangles.
What is the base of a rectangle?
there is no base for a rectangle. only triangles do. to know the sides of the rectangle you need to know the length and width of it
How do you solve special right triangles?
The answer depends on what solving is required: do you need to find the area, perimeter, angles, trigonometric rations?
Can you two acute triangles that are not similar?
i think you need to check you grammer
Are two triangles with corresponding congruent angles congruent?
No, they are similar. They may be congruent, but they need not be.
When will two right triangles be similar?
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
It appears from the name of the HL Theorem that you actually need to know that only two parts of two triangles are congruent in order to prove two triangles congruent Is this the case?
No. You can know all three angles of both and all you can say is that the triangles are similar. Or with any pair of congruent sides you can have an acute angle between them or an obtuse angle.
If two triangles have three pairs of congruent angles are the triangles guaranteed to be congruent?
No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.
What is a solid figure with one blank that is a polygon and 3 or more faces that are triangles with a common vertex?
I need help with that too!
What is the meaning of addition and subtraction of similar fraction?
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
How many triangles and trapezoids make a hexagon?
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.
How many triangles and rectangles are need to make a triangular prism?
2 triangles and 3 rectangles
How can you make a trapezoid with triangles?
You need 3,5,7,9... triangles. They have to be equilateral triangles. 1,3,5,7... need to be upside down while 2,4,6,8... have to be right side up. ______ /\ /\ /\ / \ / \ / \ /__\/__\/__\ I know, bad picture, hopefully you get the point though.
How many triangles in a triacontakaidigon?
A triacontakaidigon is a polyhedron with 32 sides. If the sides are all triangles, then there are 32 triangles in a triacontakaidigon, but a triacontakaidigon does not need to have triangular shaped sides.
