8. If the square described on one of the sides of a triangle be equal to the sum of the squares described

on the other two sides, the angle contained by these two sides is a right angle.

9. Two circles intersect: prove that, by joining the centres with one another, and with the points of

intersection, two equal triangles are thus formed.

10. Prove that if the bisectors of the angles at the base of an isosceles triangle meet within the triangls

they are equal to one another,

Class III. 4.

4. If two angles of a triangle be equal, the sides also which are opposite to the equal angles shall be

equal to one another.

5. If two triangles have the three sides of the one equal to the three sides of the other each to each

they shall be equal in all respects. (Proposition 8.)

6. To draw a straight line perpendicular to a given straight line of unlimited length from a given

point without it.

7. Any two sides of a triangle are together greater than the third side.

8. Two circles intersect: prove that if their centres be joined with one another and with the points of

intersection two equal triangles are thus formed.
