I need help with this geometry test. Its unit 5 lesson 10. I already answered them but i need someone to tell me if i got them right and if I didn't then answer them pls, i suckkk at geometry! 1. What is the area of the trapezoid? The diagram is not drawn on the scale. 9cm 4cm 5cm
A. 14cm^2
B. 20cm^2
C. 38cm^2
D. 56cm^2 (what i answered)

What are the first 4 terms in the multiplication pattern given by the formula 2×4n

Which of the following can be used to explain a statement in a geometric proof?

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)
