Answer:

Two pairs of parallel sides

Step-by-step explanation:

The given transformation performed on parallelogram RSTU = 180° clockwise rotation

Given that a rotation is a form of rigid transformation, the shape and size of the preimage RSTU will be equal to the the shape and size of the image R'S'T'U'

Therefore, RSTU ≅ R'S'T'U' and R'S'T'U' is also a parallelogram with two pairs of parallel sides.

Plz Help Brainliest To First Answer In rhombus ABCD , m∠BCE=33∘ . What is m∠ABE ?

Tamiku [17]

Answer:

57 deg

Step-by-step explanation:

Rhombus ABCD has diagonals AC and BD which intersect at point E.

The diagonals of a rhombus divide the rhombus into 4 congruent triangles.

If you find the measures of the angles of one of the triangles, then you know the measures of the angles of all 4 triangles.

Also, the diagonals of a rhombus are perpendicular.

Look at triangle BCE.

m<BCE = 33

m<BEC = 90

m<BCE + m<BEC + m<CBE = 180

33 + 90 + m<CBE = 180

m<CBE = 57

<ABE in triangle ABE corresponds to <CBE in triangle BCE.

m<ABE = m<CBE = 57

Answer: 57 deg

In parallelogram ABCD , m∠A=(2x)° and m∠B=(5x+5)° . The figure shows parallelogram A B C D with vertices named clockwise from bo

lara [203]

Answer:

The measure of angles of parallelogram are

∠A = 50° ,

∠B = 130° ,

∠C = 50° ,

∠D = 130°

Step-by-step explanation:

Given as for a parallelogram :

The vertices of parallelogram is A B C D in clockwise

The measure of angle A = ∠A = ( 2 x )°

The measure of angle B = ∠B = ( 5 x + 5 )°

Now, for a parallelogram , the sum of measure of all four angles = 360°

From The property of Parallelogram

A ) The adjacent angles are supplementary

So, ∠A + ∠B = 180°

Or, ( 2 x )° + ( 5 x + 5 )° = 180°

Or, ( 7 x + 5 )° = 180°

Or , ( 7 x )° = 180° - 5°

Or , ( 7 x )° = 175°

∴ x = $\frac{175}{7}$

I.e x = 25°

So, ∠A = ( 2 x )° = ( 2 ×25° )

I.e , ∠A = 50°

∠B = ( 5 x + 5 )°

Or, ∠B = ( 5 ×25° + 5 )°

I.e , ∠B = 130°

B ) The opposite angles of parallelogram is equal

So, ∠C = ∠A = 50°

I,e ∠C = 50°

And ∠D = ∠B = 130°

I.e ∠D = 130°

Hence The measure of angles of parallelogram are ∠A = 50° , ∠B = 130° , ∠C = 50° , ∠D = 130° Answer
