This is a great addition to your word wall or just great posters for your classroom or bulletin board. Help your students remember which term goes with what (like that orthocenter is the point of intersection of the altitudes in a triangle) with these clever mnemonic devices. You get four PDF pages, one for each term (orthocenter, incenter, centroid, and circumcenter).
Teaching tip: use the posters to introduce the students to the mnemonic devices as a way to hook them into the lesson. Have them repeat each poster at least twice and THEN go into the lesson to explain the mathematics behind it.
