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 shape is formed using 5 congruent triangles and has 5 vertices 5 angles 5 sides?
pentagon
How do you prove that the diagonals of an isosceles trapezoid are equal?
Let's draw the isosceles trapezoid ABCD, where AD ≅ BC, and mADC ≅ mBCD. If we draw the diagonals AC and BD of the trapezoid two congruent triangles are formed, ∆ ADC ≅ ∆ BDC (SAS Postulate: If two sides and the angle between them in one triangle are congruent to the corresponding parts in another triangle, then the triangles are congruent). Since these triangles are congruent, AC ≅ BD.
Can you make 2 exact triangles using exactly 9 toothpicks?
If one of the nine toothpicks is the common base of the two congruent isosceles triangles with sides formed by two toothpicks.
If you draw 2 equilateral triangles that are congruent and share a side what polygon is formed is it a regular polygon?
it should make a square leaned over
What 2 triangles are formed when split a parallelogram in half?
Two congruent triangles.
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.
What quadirlateral is formed by 2 right scalene triangles?
If the triangles are congruent and you match the hypotenera the right way, you can get a rectangle. If the triangles are not congruent, you can't even necessarily get a quadrilateral.
What shape can be formed from two congruent isosceles triangles?
A rhombus.
How many pairs of congruent triangles are formed diagonals of a rectangle?
Four.
If a diagonal is drawn in a parallelogram then two congruent triangles are formed?
True.
Choose the congruent triangles formed by diagnol ac?
abc and cda
How many pairs of congruent triangles are formed by the diagonals of a rectangle?
4
If a diagonal is drawn in a parallelogram then two congruent triangles are formed.?
Correct
Are 4 triangles formed by two diagonals of a trapezium congruent?
yes
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.
Are the triangles created when a square is divided by a diagonal isosceles?
Yes, since all the sides of a square are equal and the definition of an isosceles triangle is to have at least two congruent sides. The congruent triangles formed are 45-45-90 triangles, so the diagonal will be the longest side with the right angle formed where the two sides of the square meet.
