Differentiated Instruction for Advanced

Learners – while the other students are

figuring out the construction of perpendicular

bisector, advanced learners can be asked to

construct a perpendicular line that passes

through a given point.

Upper secondary students can be

asked to prove Viviani’ Theorem from

1600’s

Select any point inside the

equilateral triangle.

Construction perpendicular

lines to each side passing

through that point. The sum of

the perpendicular distance of

the point to the sides is equal

to the height of the triangle.

Can you prove it?

See Viviani’s Theorem from

1659.
