What else can I help you with?
Suppose you drew a diagonal in each of the following quadrilaterals rectangles trapezoid parallelogram. In which figures do triangles with a different size and shape form?
When you draw a diagonal in a rectangle or a parallelogram, it divides the shape into two congruent triangles, meaning both triangles are the same size and shape. In contrast, drawing a diagonal in a trapezoid results in two triangles that can differ in size and shape, as the bases of the trapezoid are unequal. Thus, different size and shape triangles form only in the trapezoid.
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.
What does each diagonal do to a parallelogram?
In a parallelogram, each diagonal divides the shape into two congruent triangles, ensuring that the areas of the resulting triangles are equal. The diagonals also bisect each other, meaning they intersect at their midpoints. Additionally, the diagonals can be used to determine the properties of the parallelogram, such as its symmetry and area.
Is it true that congruent triangles have the same shape?
yes it is
What shape has all congruent triangles?

What other 2d shape has congruent triangles in it?
A square and rectangle both have congruent triangles in them.
What do you call triangles that are the same size and shape?
congruent triangles

Congruent triangles have what the same?
shape and sizecorresponding sides

What shape has congruent angles?
Regular polygons have congruent angles such as squares and equilateral triangles.
Congruent triangles have the same shape and size because they will always have the same?
Congruent Triangles have the same angles and side length measures
Are all similar triangles congruent triangles?
No. For example the triangles with sides {3, 4, 5} and {6, 8, 10} are similar but not congruent.
Triangles are congruent if they have the same what?
Triangles are congruent if the lengths of their corresponding sides as well as the measures of their corresponding angles are the same.
