How burette is more accurate than measuring cylinder?
burette gives a much finer volume reading than a measuring cylinder and all the chemicals can be placed inside it at the start of the experiment.
How do you draw a hexagon that has 2 right angles 2 acute and 2 obtuse?
If 1 or 2 of the obtuse angles are 'bent into' the hexagon then you can do it.A hexagon has 720° sum of interior angles. If you have 2 right angles, then that's 180°, leaving 540° to be distributed over four angles. If the two acute angles are 89°, then that leaves 362° to be divided between two angles, so at least one of these two angles will need to be greater than 180°. Below is my text graphics attempt of one possibility (ignore the 'dot'). Note that both of the obtuse angles are greater than 180°:|\_/||__.|Look at the related link to play with different angle possibilities for polygons.
How do you draw a pentagon with 2 right angles 1 reflex and 2 acute angles?
It would look like a hut.
How many triangles can you break a 50-sided polygon into using the diagonals that all start at the same vertex?
48 because (50-2)*180 = sum of interior angles
How do you draw a quadrilateral with 1 reflex 1 obtuse and 2 acute angles?
Well, honey, to draw a quadrilateral with 1 reflex, 1 obtuse, and 2 acute angles, you'll need to start by sketching a shape with 1 angle greater than 180 degrees (that's your reflex angle), 1 angle greater than 90 degrees (that's your obtuse angle), and 2 angles less than 90 degrees (those are your acute angles). Just make sure all the angles add up to 360 degrees, and you'll have yourself a sassy quadrilateral!
