The vertical cross-sectional shapes of this prism are all congruent triangles?
false
Triangles that have their corresponding parts congruent?
Are congruent triangles.
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.
What are three ways that you can prove that triangles are congruent?
If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.
How many pairs of congruent triangles are formed by the diagonals of a rectangle?
4
Is a rectangle made up of congruent shapes?
I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.
What shapes can you make out of two congruent right-angled triangles?
a rectangle
The vertical cross-sectional shapes of this prism are all congruent triangles?
false
What figure is formed when you put two congruent triangles together?
Figure that are congruent are shapes are the same size and shape. So when two formed congruent triangles are both together they fit just right.
Number of pairs of congruent triangles in a square?
4 congruent pairs
The vertical cross-sectional shapes of this prism are all congruent triangles.?
A right triangular prism.
How can you tell both shapes are similar?
to prove two triangles are similar, get 2 angles congruent
Name the type of special quadrilateral that will appear when you join two congruent equilateral triangles?
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
What is the problem if angles are not congruent?
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
Do the vertical cross sectional shapes of a triangular prism have all congruent triangles?
Yes the triangular cross-section area is congruent throughput the prism.
Triangles that have their corresponding parts congruent?
Are congruent triangles.
What shapes are the faces of a square pyramid?
A square pyramid has a square base and four congruent triangular faces.
