GUIDELINE FOR GRINDING WOODTURNING TOOL ANGLES

The sum of these angles is 360o a oo+ x + bo + y = 360o x a b y 4 The opposite angles created by intersecting lines are always equal: a=b, x=y o 2a + 2xo = 360o 5 Two perpendicular intersecting lines always form four 900 (“right”) angles a x y b 6 If the sum of any two angles equals 180o, those angles are supplementary If you

estimate and then find examples of right angles in the classroom • Middle ability - Ask the children to get into pairs and use the angle sticks The angle sticks can be moved to make different types of angles Ask the children to test each other in pairs - one can show an angle while their partner says if it's obtuse, right, acute and so on

PROPERTIES AND PROOFS OF SEGMENTS AND ANGLES

, since the two nonoverlapping angles share ray AD - Statement #6: Since the measurement of angle BAD equals the sums of the measures of angles EAD and CAD, and this sum is equal to the measure of angle EAC, then the transitive property may be applied Thus, the measurement of BAD equals the measurement of EAC (If a = b and b = c, then a = c )

angles Another way to state this answer is mp⊥ * When referring to perpendicular lines on paper, draw mini-perpendicular lines between the names for the lines as shown in the previous paragraph When referring to perpendicular lines online, just type in “line m is perpendicular to line n”
