KL and are perpendicular. Explain your answer using the definitions you have learned. A pair of vertical angles can be complementary. See the second picture. Complementary angles must be acute. If the diagonals of a quadrilateral are congruent, the quadrilateral is a rhombus. 13. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle. The vertex angle of an isosceles triangle is always acute: FALSE, since it can be acute or obtuse 2. (Choose 2… If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. 90° (c)55° 1. Name a pair of complementary angles. Linear pair forms two supplementary angles. If False, give a counterexample. 1. If two lines intersect and one of the angle so formed is a right angle, then vertically opposite angle is also right angle and also other two angles are right by angle linear pair. Step-by-step explanation: True, The opposite angles of a quadrilateral in a circumscribed circle is always supplementary. Explain. a. 37.

Two acute angles can be supplementary.\nb. 1. say whether it is true or false with reasons (i) Can two right angles be complementary? 4. 2. Two obtuse angles can be supplementary.\" Two acute angles can be supplementary. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. By theorem, sum of the opposite angles of a cyclic quadrilateral is 180°. Sometimes – could also be a trapezoid. Always true, either by HL or by SAS. b. If False, give a counterexample. Answer. Which word best completes this statement? If two angles are supplementary, then their sum equals 180 degrees. Is this statement true or false The sine of an angle in a right triangle is the ratio of the length of the side adjacent to that angle … Here we say that the two angles complement each other. So, the statement is true. Which polygon will always be irregular? 14. If the diagonals of a quadrilateral divide each angle into two 45-degree angles, the quadrilateral is a square. If two parallel lines are intersected by a transversal, then each pair of corresponding angles so formed is (a) Equal (b) Complementary True or False??? o True o False Consecutive interior angles have corresponding positions in the same side of the transversal. In the diagram below the two angles α (alpha), and β (beta) are vertical angles and α = β. Complementary and Supplementary Angles. If x and y are supplementary angles, then x is right. Question 60. Supplementary angles a and b do not form linear pair. e.g. False; they could be right angles. If two segments are congruent, then their lengths are equal. As we know that quadrilateral in a circumscribed circle is cyclic quadrilateral. Click hereto get an answer to your question ️ \"State whether the following statements are true or false.\na. the angles. Vertical angles are also called opposite angles. Always. Complementary angles are those that sum up to 90^o. If a parallelogram is equiangular, it is equilateral.

Complementary Angles. Question 2. 30. Suppose if one angle is x then the other angle will be 90 o – x. As can be seen from the figure above, when two lines intersect, four angles are formed.Each opposite pair are called vertical angles and are always congruent.The red angles ∠ JQM and ∠ LQK are equal, as are the blue angles ∠ JQL and ∠ MQK. Prove that if in two triangles,two angles and the included side of one triangle are equal to two angles and the included side of the other triangle,then two triangles are congruent. (b) When a transversal cuts two lines such that pairs of alternate interior angles are equal, then the lines have to be parallel. Two adjacent angles can be complementary.\nc. (iii) Can two adjacent angles be complementary? Adjacent angles are angles that are adjacent to each other. If two angles measure 90, then the angles are complementary. In an obtuse triangle all the angles are obtuse. Conjecture: ∠A is supplementary to ∠C. a. true b. false 3. because 90° + 90° = 180°, as it satisfies the condition of supplementary angles. Supplementary angles must be obtuse. 1.
