Write the names of seven angles.
Answers
Hey there !
Solution:
1. Acute Angle: Angles which have measure less than 90° are termed as acute angles. Their range can be given as: 0° < Acute Angle < 90°. Here 0° and 90° are not included. According to the attachment, ∠ACD is acute angle.
2. Right Angle: Angle which are made by two straight intersecting lines are called right angles. It has a measure of 90°. According to the attachment, ∠ADC = 90°
3. Obtuse Angle: Angle which has a measure greater than 90° and less than 180° is termed as an obtuse angle. It's range can be given as:
90° < Obtuse Angle < 180°, where 90° and 180° are not included.
4. Straight Angle: Angle which forms 180° or the angle made by a straight line is termed as a Straight angle. It has a measure of 180°.
5. Reflex Angle: Angle which is greater than 180° but less than 270° is termed as Reflex angle. It has a range between 180° < Reflex Angle < 270°.
6. Complete angle : Angle which makes a complete rotation by forming a circle is termed as a Complete angle. It measures 360°.
7. Complementary and Supplementary Angles: Angles when added with each other, if they sum up to 90° then they are known as Complementary angles. E.g. 45° + 45° = 90°. Here 45° is the complement of 45°.
Supplementary Angles are the angles which when added to each other, sum up to 180°. E.g. 45° + 135° = 180°. Here 45° is the supplement of 135°.
Angles in the diagram are: ∠ABD, ∠ACB, ∠BAC, ∠BDA, ∠CDA, BAD and ∠CAD.
Hope my answer helped !
angle BDA = 90°
angle ADC = 90°
angle ACD = 45°
angle CAD = 45°
angle DAB = 45°
angle DBA = 45°
I hope it is the answer
