Side 29 - If two triangles have two angles and the included side of the one, equal to two angles and the included side of the other, each to each, the two triangles will be equal.
Side 18 - A right-angled triangle (Fig. 24) is any triangle having one right angle. The side opposite the right angle is called the hypotenuse.
Side 19 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
Side 30 - If two triangles have the three sides of the one equal to the three sides of the other, each to each, the triangles are congruent.
Side 29 - A straight line falling on parallel straight lines makes the alternate angles equal to one another, the exterior angle equal to the interior and opposite angle, and the interior angles on the same side equal to two right angles...
Side 32 - The straight line which bisects the vertical angle of an isosceles triangle is perpendicular to the base.
Side 20 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds.
Side 19 - A diameter of a circle is a straight line drawn through the centre, and terminated both ways by the circumference.
Side 19 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.
Side 35 - If two triangles have two sides and the included angle of the one, equal to two sides and the included angle of the other, each to each, the two triangles will be equal in all their parts." Axiom 1. "Things which are equal to the same thing, are equal to each other.
