Right triangle LMN is graphed on a coordinate plane and its smallest angle measures only 24°. LMN is dilated with scale factor r = 2, then translated down 5 units to create image L'M'N'. If the angle measures of L'M'N' were arranged from least to greatest, what would be the measure of the middle angle?
The measure of the smallest angle in triangle LMN is 24°.
When triangle LMN is dilated with a scale factor of 2, all angles remain the same. Thus, the smallest angle in triangle L'M'N' is also 24°.
After the translation down 5 units, the angles in triangle L'M'N' remain the same. Therefore, the middle angle in triangle L'M'N' (the only angle left) is also 24°.
Therefore, the measure of the middle angle in triangle L'M'N' is 24°.
