**012 How to draw acute obtuse and reflex angles YouTube**

I need to construct a triangle from given base, obtuse angle adjacent to base and difference of two other sides. Let us try to analyze the scenario. We are given base BC, obtuse $\angle\text{ACB}$ adjacent to base BC, and BD equal to AB minus AC.... Step 2: Using a protractor draw an angle of 57° from Point A. Mark the Point D so that AD = 6 cm. All sides of a rhombus are equal. Step 3: Using a ruler and a set square draw …

**Fourth grade Lesson Right Acute & Obtuse Angles**

22/01/2009 · Best Answer: an obtuse angle is greater than 90 degrees, so 2 obtuse angles would be greater than 180 degrees. the sum of all the angles in a triangle is always exactly 180 degrees, not more. you can also see this by drawing. It is impossible to draw any triangle with 2 obtuse angles. hope this helps :)... Show them how to use the protractor to draw and measure a 90° angle and point out that all right angles measure 90°. Finally, have students use the protractor as an angle finder to classify some angles modeled with pipe cleaners. Students should notice whether angles are acute, right, or obtuse, and whether their measures are greater or less than 90°. After they have made a few comparisons

**Mathematical Mysteries Trisecting the Angle plus.maths.org**

Angle represents the arc in degrees (for example if the angle is 90°, we get a quarter of an ellipse) Dash represents the thickness of the line The following example illustrates this functionality: the result is an arc of circle of 150° with a radius of 3 cm: how to choose wiper blads We saw in this module how to use the unit circle to give meaning to the sine and cosine of an obtuse angle. This definition can be extended to include angles greater than 180° and also to negative angles.

- This fourth grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole circle. The lesson contains many varied exercises for students.
- Obtuse is an angle that is bigger than a right angle; it's 'fat' - obtuse sounds like obese, which means fat. Acute is an angle smaller than a right angle; small things can be cute - a cute angle
- Its pretty easy to draw them just remember that a right angle is an angle thats exactly 90degress ,an obtuse angle is greater than 90 but less than 180 and acute is less than 90degress
