Q. A figure containing ∠EFG is dilated by a scale factor of 2 to form a new figure which contains ∠E′F′G′.∠EFG measures 59∘. What is the measure of ∠E′F′G′ ?Answer: m∠E′F′G′=□∘
Understand Dilation Effect: Understand the effect of dilation on angle measures.Dilation changes the size of the figure but does not alter the measure of the angles. Therefore, the measure of ∠EFG will be equal to the measure of ∠E′F′G′ after the dilation.
Identify Given Angle Measure: Identify the given angle measure of ∠EFG. The problem states that ∠EFG measures 59 degrees.
Determine Measure of E'F'G': Determine the measure of ∠E′F′G′. Since dilation does not change angle measures, the measure of ∠E′F′G′ will be the same as the measure of ∠EFG. Therefore, m∠E′F′G′=59 degrees.
