Concept/skill: 
Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.

Problem/activity:
Find the general solution for:
$${\mathrm{cos}\left({\pi\over2}+x\right)=\mathrm{tan}{\pi\over4}}$$


Answer: 
No. This problem does not directly teach how side ratios in right triangles lead to definitions of trigonometric ratios. Instead, it involves solving a trigonometric function.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

Required Preparation
Materials to Gather
Colored pencils, crayons, or markers
Number cards 0–10
Paper clips
Materials to Copy
Blackline Masters
Tic Tac Round Stage 2 Gameboard
Tic Tac Round Stage 2 Spinner

Narrative
Students remove the cards that show 10 before they start. Then they choose six number cards and make a six-digit number. They spin the spinner to get a place value to round to. Students write their number in any space on the board, each partner using a different color. The first player to get three in a row wins.
