Geometry Q2

• Adjacent angles are two angles in the same plane that has a common vertex and side but do not have any interior points in common
• Linear pair are two angles that are adjacent to each other and has their opposite side are opposite rays.
• Supplementary angles are angles that has a sum of 180 degrees.
• A right angle is an angle that has a measurement of 90 degrees.
• Complementary angles are two angles that has a sum of 90 degrees.
• Reflexive property means that every angle is congruent to itself.
• Congruent angles are two angles that has an equal measurement.
• Sketch is a freehand sketch of sn object done without the use of geometric tools.
• Draw is the careful and accurate drawing done with the use if geometric tools.
• Construction is any drawing that is restricted to use only a compass and a straight edge.
• Conditional statements are known as the "If-then Statements". It is one basic type of logical statement.
• The conditional statement in symbol is "If p, then q".
• The converse statement in symbol is "If q, then p"
• The inverse statement in symbol is "if ~p, then ~q"
• The contrapositive statement in symbol is "If ~q, then ~p"
• Converse statement is formed by interchanging the hypothesis and the conclusion of a conditional statement.
• Inverse statement is the negation of both the hypothesis and the conclusion.
• The two types of geometric proof is the two column proof and the paragraph proof.
• Equiangular triangle is a type of triangle where all angles are congruent.
• The right triangle is a type of triangle whose angle is a right angle.
• The hypotenuse is the side opposite of the right angle.
• The two sides beside the right angle in a right triangle is called legs.
• The acute triangle is a type of triangle whose angle are all acute.
• The obtuse triangle is a type of triangle with an obtuse angle and two acute angles.
• The 4 classifications of triangle according to its angle is the Equiangular triangle, the right triangle, the acute triangle, and the obtuse triangle.
• The 3 classification of triangle according to its side is the Isosceles triangle, equilateral triangle, and the scalene triangle.
• The Isosceles triangle is a type of triangle with 2 congruent sides. It has a side that is called the base.
• An Equilateral triangle is a triangle in which all three sides have the same length.
• The scalene triangle is a type of triangle where all three sides have different lengths and all three angles have three different measures.
