Grade 9 Math | Construct and Justify Secondary Parts of Triangle Second Term (Term 2) Week 5

What are the secondary parts of a triangle? How to construct the secondary parts of a triangle? How to draw the secondary parts of a triangle? How to construct median of a triangle? How to construct the altitude of a triangle? How to construct perpendicular bisector of the sides of triangle? How to construct angle bisector of a triangle? The learning competency of this lesson is construct and justify the construction of segments, angles and triangles, including, but not limited to, the triangle’s secondary parts and centers, using the triangle congruence postulates and theorems. The learning objectives are Identify the parts of a triangle, including its vertices, sides, angles, medians, altitudes, angle bisectors, and perpendicular bisectors; Describe the different centers of a triangle: centroid, circumcenter, incenter, and orthocenter. Draw the secondary parts of triangles such as medians, altitudes, angle bisectors, and perpendicular bisectors; Analyze the relationships between the secondary parts and centers of a triangle. This video lesson discussed and illustrates the different secondary parts of a triangle like median, angle bisector of triangle, perpendicular bisector of triangle and altitude of triangle. This lesson is based on the revised K to 10 curriculum for grade 9 mathematics. #Term2 #Secondterm #Week5 #Grade9mathematics #Mathematics9 #Howtoconstructsecondarypartsoftriangle? #Howtoconstructaltitude? #Howtoconstructmedianoftringle? #Revisedkto10
