Students create perpendicular bisectors. In this geometry lesson plan,students use a straight edge and protractor to create a perpendicular bisector. They graph line on the TI and analyze it.

Tenth graders investigate parallel lines and the angles formed when cut by a transversal. In this geometry lesson plan, 10th graders construct perpendicular lines and discuss midpoint, segments and perpendicular bisectors. They relate...

Learners investigate points and angle bisectors. In this geometry activity, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Under which conditions can a triangle be classified as isosceles? High schoolers practice identifying isosceles triangles and special line segments, including angle bisectors, medians of triangles, and perpendicular bisectors of sides of...

Your geometry learners use their knowledge of various geometric concepts to write proofs. Starting with givens containing parallel line segments with transversals and triangles and quadrilaterals, and the mid-point and distance formulas;...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Students construct perpendicular lines. In this geometry lesson, students use a compass and straight edge to do construction. They start from a point to a line.

Students practice constructing a perpendicular bisector. During a demonstration, they discover the meaning of bisector and perpendicular and answer questions why these steps shown are going to work. They use a compass and a...

Students identify the special segments of triangles, the median, angle bisector, altitude, and perpendicular bisectors.

Teach how to differentiate between chords and perpendicular bisectors. In this geometry activity, students relate the properties of chords and circle to solving right triangle. They define what makes two chords congruent in side a circle.

Students investigate special triangles and circles. In this geometry lesson, students construct a perpendicular bisector and discuss angles of a triangle. They find the angle bisectors, vetex and the types of circle constructed.

Students identify the circumcenter of a triangle. In this geometry lesson plan, students construct a perpendicular bisector using a straight edge and a compass. They differentiate between triangles and collinear points.

Tenth graders find the incenter of a triangle. In this geometry lesson, 10th graders define the way to create an incenter with an angle bisector. They differentiate between incenter and incircle.

Pupils make conjectures of intersecting circles. In this geometry instructional activity, students observe circles and their position in space. They investigate and observe two and three dimensional objects.

Students identify properties of circles. In this geometry activity, students identify the center of two intersecting circles.They use Cabri software to create circles and move it around to make observation.

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.
