Look at these triangles. A figure contains six labeled triangles of different sizes. Triangle A has one obtuse angle, two angles that appear congruent, and two sides that appear congruent. Triangle B has three angles that appear to be congruent and three sides that appear to be congruent. Triangle C has three angles that appear to be congruent and three sides that appear to be congruent. Triangle D has one obtuse angle and two angles that appear to have different measures. The three sides all appear to have different lengths, with the side opposite the obtuse angle appearing to be the longest side. Triangle E has three angles that appear to be congruent and three sides that appear to be congruent. Triangle F appears to have one right angle and all three side lengths appear to be different. Which triangles are similar? (Select all that apply.)

3. The top and bottom of a five-foot high snowplow are to be attached to two steel braces of different lengths that meet at an angle of 44 degrees.

On the map, Atlanta, Miami, and New Orleans form a triangle whose sides are shown in the figure below. The actual distance from Atlanta to New Orleans is 420 miles.   The image shows a triangle. Each angle is labeled, clockwise, “Atlanta”, “Miami”, and “New Orleans”. The side that extends from Atlanta to Miami is labeled 3 inches. The side that extends from Miami to New Orleans is labeled 3.4 inches and the side extending from New Orleans to Atlanta is labeled 2.1 inches. What is the actual distance from Atlanta to Miami?
