in this picture, b and f are midpoints.\nce = 90\nbf = ?
Answer
Answer:
45
Explanation:
Step1: Identify Midsegment Theorem
Since B and F are midpoints, BF is a midsegment of the relevant triangle (or trapezoid, but using midsegment concept). The midsegment theorem states that the midsegment is parallel to the base and half its length.
Step2: Apply the Theorem to CE
Given ( CE = 90 ), by the midsegment theorem, ( BF=\frac{1}{2}CE ).
Step3: Calculate BF
Substitute ( CE = 90 ) into the formula: ( BF=\frac{90}{2}=45 ).
