Investigating Lengths of Segments in a Triangle

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The dynamic nature of Cabri Jr. allows learners to manipulate the figures as they make and test conjectures relating to the length of the midsegment.

After 28 years of teaching English, I signed up to teach grade nine art. My school only has 15 teachers and the students were losing out on opportunities to explore their creativity. Having access to the lessons on Lesson Planet has helped me to cover the curriculum while having fun with all the different ways of teaching the subject. To say this site is a blessing is an understatement!
