Constructing
an Altitude - Construct an equilateral triangle. Then construct one of its
altitudes. If the sides each have length 1, how long is the altitude - Construct an equilateral triangle. Then construct one of its
altitudes. If the sides each have length 1, how long is the altitude
Geometric
mean - Prove that the length of the altitude to the
hypotenuse of a right triangle is the geometric mean of the lengths of the
segments into which the altitude partisans the hypotenuse.
Proofs -
Triangles - 1- if we have a triangle ABC, then prove
that the internal and external bisectors of the angle of a triangle are
perpendicular (assume for angle A) 2- prove that given triangle ABC with the
altitude ...
Size of
Triangles - 28. Find the area and perimeter of an
equilateral triangle whose altitude measures 6 cm. 29. If the area of an
equilateral triangle is 100 sq cm, find the length of a side.
Geometry/construction - -construct triangle ABC given the length of one side BC, the length
of the median to BC and the length of the altitude from B
