b Use the fact that the thickness of the major stroke was 112 the height of the letter.
A
a See solution.
B
b 1/4 cm
a We are asked to explain why the bar through the middle of the A is half of the space between the outside bottom corners of the sides of the letter. First, let's recall the Triangle Midsegment Theorem.
A midsegment of a triangle is parallel to one side of the triangle, and its length is one half the length of that side.
Since we are given that the bar is in the middle of the letter and we know that it is parallel to the sides of frame, we can say that it is a midsegment of a triangle that creates letter A.
According to the above theorem, this is the reason why the bar is half of the space between the outside bottom corners.
b In this part we are asked to find the thickness of the major stroke if the letter were 3 centimeters tall. Since we know that the thickness of the major stroke of the letter was 112 the height of the letter, we will multiply 3 by 112.
