A plane is a surface such that a straight line joining any two of its points lies
wholly in the surface. 10. A rectilinear figure is a figure which lies wholly in one
plane and which represents a surface bounded by segments of straight lines. 11.

A diameter bisects the circle and the surface inclosed, and conversely. 9. If two
central angles of the same circle or of equal circles are equal, the angles have
equal arcs; and if two central angles are unequal, the greater angle has the
greater ...

Obviously we cannot draw a figure which shall represent such a surface; and
hence when we wish to show a plane, we may represent it by a thin rectangular
solid seen obliquely, as in any of the three ways shown below. Since the student
has ...

Σελίδα 7 - The line joining the midpoints of two sides of a triangle is parallel to the third side and equal to one-half of it.
Σελίδα 40 - A line which joins the midpoints of two sides of a triangle is parallel to the third side and equal to half of it.
Σελίδα 176 - The areas of two triangles which have an angle of the one equal to an angle of the other are to each other as the products of the sides including the equal angles.
Σελίδα 10 - If two triangles have two sides of the one equal respectively to two sides of the other, but the included angle of the first greater than the included angle of the second, then the third side of the first is greater than the third side of the second. Given A ABC and A'B'C...
Σελίδα 15 - In any triangle, the square of the side opposite an acute angle is equal to the sum of the squares of the other two sides diminished by twice the product of one of those sides and the projection of the other upon that side.
Σελίδα 77 - The height of a cone is the perpendicular distance from the vertex to the plane of the base.
Σελίδα 3 - If the first of three quantities is greater than the second, and the second is greater than the third, then the first is greater than the third.
Σελίδα 24 - If a straight line is perpendicular to each of two other straight lines at their point of intersection, it is perpendicular to the plane of the two lines.
Σελίδα 16 - If two chords intersect in a circle, the product of the segments of one is equal to the product of the segments of the other.
Σελίδα 15 - The sum of the squares of two sides of a triangle is equal to twice the square of half the third side increased by twice the square of the median upon that side.
