Part 1:"The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet

tall and 4 feet wide. They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot.
Do they have enough money to cover the cost of making the window?" (PART 1 IS DONE)


Part 2:"A local community member sees the school’s stained glass window and really likes the design. They ask the students to create a larger copy of the window using a scale factor of 3 (9 feet tall and 12 feet wide). Would $450 be enough to buy the materials for the larger window?"

Part 3:"Make your own stained glass window design that could be made for less than $450. Show your thinking."

These triangles ARE similar! Which reason proves it?
andrew-mc [135]

Answer:

SAS

Step-by-step explanation:

From the image attached below, in triangle ABC, AB = 15, AC = 20 while in triangle ADE, AD = 12 and AE = 16

Two triangles are said to be similar if they have the same shape, that is either their corresponding angles are the same or their corresponding sides are proportional.

For both triangle ABC and triangle ADE, they have the same angle which is ∠A. Also:

\frac{AD}{AB}=\frac{12}{15}=\frac{4}{5}

\frac{AE}{AC}=\frac{16}{20}=\frac{4}{5}

Since two sides of triangle ABC are in the same proportion as two sides of triangle ADE and they have the same angle, therefore they are similar based on the SAS  (side-angle-side) similarity
