The sweet, lazy whistles of Eastern Meadowlarks waft over summer grasslands and farms in eastern North America. The birds themselves sing from fenceposts and telephone lines or stalk through the grasses, probing the ground for insects with their long, sharp bills.
A median of a triangle is a straight line through a vertex and the midpoint of the opposite side, and divides the triangle into two equal areas. The three medians intersect in a single point, the triangle's centroid or geometric barycenter, usually denoted by G.wo triangles are said to be similar if every angle of one triangle has the same measure as the corresponding angle in the other triangle. The corresponding sides of similar triangles have lengths that are in the same proportion, and this property is also sufficient to establish similarity.
Right Triangles. A right triangle is a triangle where one of its angles is a right angle (i.e. 90Â°). The other two angles are acute angles. You may have noticed that the side opposite the right angle is always the triangle's longest side. It is called the hypotenuse of the triangle.The other two sides are called the legs.or example, in trigonometry and also in the Pythagorean Theorem. The lengths of the sides of a right triangle are related by the Pythagorean Theorem. There are also special right triangles where the sides are of certain fixed ratios. A right triangle can be isosceles if the two legs are equal in length.
