A rectangle is inscribed in a square creating four isosceles right triangles.. If the total area of these four triangles is 200, what is the length of the diagonal of
The second has an inverted (shaded) equilateral triangle inscribed inside an equilateral triangle as shown.. Each subsequent figure in this sequence is obtained by inserting an
When the number q is removed from the list of numbers of which the average was taken, the mean (average) increases by 2.. ABC is an equilateral triangle with sides of 2
The triangle formed when the centres of the circles are joined to one of the points of intersection is equilateral, with sides equal to the radii of the circles.. The line joining
– If the circle actually touches one pair of opposite sides, then its radius is half the distance between opposite sides, so in order to be contained entirely inside the hexagon,
Thus, the perimeter of the field is equal to the total length of the two straight sides, or 200 m, added to the circumference of a circle with diameter 60 m, or π (60) m.. Thus,
There are seven shapes formed of three a four equilateral triangles connected edge-to-edge, as shown in the 2×5 chart below. For each of the numbered spaces in the
In the space provided, construct an equilateral triangle ABC with sides equal to the length of MN below. As shown in Figure 1, construct a circle inside the triangle ABC, so that
