Jillian plans a pillow pattern before sewing. The parallelogram in the center of the pattern has a base length of 9 inches and a height of 7 inches. She needs to find the area of the fabric surrounding the parallelogram pattern. Which statements below should she apply when solving this problem? Check all that apply.
option one: A parallelogram is inside of a rectangle with height 8 inches and base 16 inches
option two: The parallelogram has a base length of 16 inches and a height of 8 inches.
option three: The area of the parallelogram is (9) (7) = 63.
option four: The total area of the block is 128 square inches.
Option 5: The area surrounding the parallelograms can be found by adding 63 to 128.
Option 6: The area surrounding the parallelogram can be found by subtracting 63 from 128.

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
