What do you mean by isosceles triangle?
: a triangle in which two sides have the same length.
How do you construct the centroid of a triangle?
How to Construct a Centroid of a Triangle
- Draw a triangle.
- Measure one of the sides of the triangle.
- Place a point at the midpoint of one of the sides of the triangle.
- Draw a line segment from the midpoint to the opposite vertex.
- Repeat steps 2-4 for the remaining two sides of the triangle.
What construction do you need to use to construct a median?
A median of a triangle is a line segment from a vertex to the midpoint of the opposite side. This can be done by first constructing a perpendicular bisector on the side of the triangle opposite the desired vertex, and marking the point at which the bisector intersects the side of the triangle.
How many medians does a triangle have?
A triangle has three medians. They are lines linking each vertex to the midpoint of the opposite side. We first find the midpoint, then draw the median. A Euclidean construction. Math Open Reference HomeContactAboutSubject Index Medians of a Triangle This page shows how to construct the medians of a trianglewith compass and straightedge or ruler.
How do you prove two triangles are equal in area?
From the two areas we see that FE=FE (the two triangles have the same height). Also AM=MB (M is the midpoint of AB, since AM is the median of the triangle. This then means that the two triangles are equal in area. Now let us consider two medians.
How do you show that the three medians are concurrent?
From above we know that the median BO intersects with the median AN in G, therefore G must be the common point where all the three medians are meeting. So the three medians are concurrent.
What does the second median divide the Green and yellow triangles?
We notice that the second median divides the green and yellow triangles in the ratio 1:2. We can write a conjecture here, If a median one median of a triangle is drawn, the second median to be drawn will divide the areas of the two triangles formed by the first median in the ratio 1:2.
