djyliett [7]

Answer:

Properties of rhombus

. all the properties of a parallelogram( apply the ones that matter hair are parallel sides opposite angles congruent and consecutive angles are supplementary)

. all sides are congruent by definition

. the diagonals bisect the angles

. the diagonals are perpendicular bisectors of each other

Properties of rectangle

. all the properties of parallelogram apply (the ones that matter hair are parallel sides, opposite sides are congruent, and diagonals bisect each other)

. all angles are right angles by definition

. the diagonals are congruent

Properties of square

. all the properties of a rhombus apply( the ones that matter have a parallel sides diagonals are perpendicular bisector of each other and diagonals bisect the angles)

. All the properties of rectangle apply (the only one that matter where is diagonals are congruent)

Fill in the missing reason in the proof. Help plss
Nostrana [21]

The missing reason in the proof is SAS -side angle side postulate

<h3>How to find the missing proof in congruent triangles</h3>

A triangle is said to be congruent if the sides and angles are similar. The notations are explained as follows:

Using two triangles say AA and BB as instance

SAS : side angle side: this means that the two sides  of triangle AA is equal to the two sides of triangle BB. For the angle it should be the angle between the two equal sides, that is to say the angle where the two sides intersect.

This is the correct option for the question asked given that

line AB ≅ AC ( first statement )  = Side

< B ≅ < D ( fourth statement ) = Angle

line BD ≅ CD ( third statement )  = Side

This represents the side angle side postulate which is one of the postulates required to prove that triangles are equal

Tia uses 3/4 cup of pumpkin to make 1 1/4 pounds of dog treats. How much pumpkin does Tia use to make 1 pound of treats?
irina1246 [14]

Answer:

4/5 cups  to make 1 pound of dog treats

Step-by-step explanation:

3/4 cups : 1 1/4 pounds

x cups : 1 pound

Cross multiply

3/4 * 1  = 1 1/4  * x

x = 3/4 / 1 1/4

= 3/4  /  5/4

= 3/4 * 4/5

= 3/5 cups
