Hi. Today we're gonna talk more about parallelogram sze unquestioned, for it gives us a parallelogram that looks like this. Remember toe Always label your vergis is clockwise or counterclockwise. They've done so for us, but it's very, very important to remember. Okay? And they also gave us that this was 30 degrees so unquestioned, for they're asking for the measure of angle. Be the ratio of the measure angle B to the measure Angle. Um, see measure angle B to measure of angle. See in a parallelogram. The opposite angles are equal. The opposite angles are equal. Also the consecutive angle. So these air called opposite angles and these air cool consecutive angles. The consecutive angles are supplementary are supplementary. You could think of a parallel line. Many DeParle a line units. If this is a trans versa, ll right here thes air, same side interior angles with 1 30 the 1 50 So now it ask for the ratio of the measure angle B to the measure of angle see. So again, a ratio is just a division problem. So the measure of Angle B is 1 50 over the measure Angle C, which is 30 which is a 5 to 1 ratio

Hi. Today we're gonna talk more about parallelogram sze unquestioned, for it gives us a parallelogram that looks like this. Remember toe Always label your vergis is clockwise or counterclockwise. They've done so for us, but it's very, very important to remember. Okay? And they also gave us that this was 30 degrees so unquestioned, for they're asking for the measure of angle. Be the ratio of the measure angle B to the measure Angle. Um, see measure angle B to measure of angle. See in a parallelogram. The opposite angles are equal. The opposite angles are equal. Also the consecutive angle. So these air called opposite angles and these air cool consecutive angles. The consecutive angles are supplementary are supplementary. You could think of a parallel line. Many DeParle a line units. If this is a trans versa, ll right here thes air, same side interior angles with 1 30 the 1 50 So now it ask for the ratio of the measure angle B to the measure of angle see. So again, a ratio is just a division problem. So the measure of Angle B is 1 50 over the measure Angle C, which is 30 which is a 5 to 1 ratio
