26.) Construct the inscribed and
circumscribed circles of a triangle,
and prove properties of angles for
a quadrilateral inscribed in a
circle. [G-C3]
26.) Construct the inscribed
and circumscribed circles of a
triangle, and prove properties
of angles for a quadrilateral
inscribed in a circle. [G-C3]
10.) Prove theorems about
triangles. Theorems include
measures of interior angles of
a triangle sum to 180o, base
angles of isosceles triangles
are congruent, the segment
joining midpoints of two sides
of a triangle is parallel to the
third side and half the length,
and the medians of a triangle
meet at a point. [G-CO10]

properties of perpendicular
bisectors to find the
distance from the vertices

triangle.
Students will be given
problems out of the book to
work either individually or
with a partner as time
permits.

individually or with a
partner as time permits.
Introduce students to
the centroid theorem
and how to use it to find

segments.
Introduce students to
the orthocenter of a
triangle and how to find
it given the dimensions
of a triangle (using the
coordinate plane).
Introduce students to
the triangle
midsegments theorem
and how it is used to
find segment lengths.
